Introduction to Intercept Calculator:

The x and y intercept calculator is a powerful tool that helps you to find the carestain points where they cross the x-axis and y-axis from the given plane. Our tool is used to determine the intercept for different types of equations in a run of time.

Intercept Calculator with Steps

When you find the given solution of the equation for the intercept method, you get confused in doing complex calculations manually. To get rid of this situation, you need an x and y intercept finder that provides you with a correct solution for the intercept problem from the given equation.

What is an Intercept?

An intercept is a method to find the intercept point where coordinate axes are met on a graph in linear algebra. There are two types of intercepts which are the x-intercept and the y-intercept for the slope of the equation

The x-intercept is found when you take the value of y which is equal to zero in the given equation. Similarly, the y-intercept is found when you put the value of x as equal to zero.

These intercepts provide you insights and the behavior of the given function. The x & y intercept calculator expresses the x-intercept in the following form:

Set y to 0:

$$ 0 \;=\; mx + b $$

Solve for x:

$$ mx \;=\; -b $$

$$ x \;=\; -\frac{b}{m} $$

The y-intercept can be expressed as,

Set x to 0:

$$ y \;=\; m(0) + b $$

Solve for y,

$$ y \;=\; b $$

How to Calculate Intercepts?

When calculating the intercepts of an equation, the x intercept and y intercept calculator finds two points where the graph of the equation crosses the x-axis and y-axis.

Let's understand how to find x and y intercepts in steps. These steps are used to calculate x and y intercepts accurately.

To y-intercept

To know how to calculate the y-intercept for the given equation, follow the given steps which are:

Step 1:

First, you need to identify whether the given equation is written in the standard form of the slope-intercept form as y = mx + b or not. If it is not then rewrite the given equation in standard form (in linear).

Step 2:

Put x = 0 in the slope of equation y = mx + b, to find the intersection point where they met from the equation.

Step 3:

Solve the equation to find the y-value points for the slope of the equation.

Step 4:

After finding the value of the y axes, the y-intercept from the given equation, you get the points that pass through a line during the intersection on the y-axis as (0, y).

To x-intercept

To find the x-intercepts for the equation some steps should be followed. Let’s understand how the x and y intercepts calculator solves the equation accurately.

Step 1:

First, start with the equation of slope y = mx + b, and see if the given equation is written in the slope of the equation pattern or not.

Step 2:

Put y = 0, to find the value of x, because of the x-intercept, the graph crosses the x-axis.

Step 3:

After that solve the equation for the x value for the slope on the graph.

Step 4:

Lastly, you get the point (x, 0) at the x-axis from the given equation of the slope.

Solved Example of Intercept

The x y intercept calculator will help you calculate x and y intercepts but its necessary for you to understand how to find x and y intercepts manually so an example is given below,

Example: Find x and y intercepts

$$ y \;=\; -3x + 9 $$

Solution:

For x intercept y = 0

$$ y \;=\; -3x + 9\; \; \; Set \;y \;=\; 0 $$

$$ 0 \;=\; -3x + 9 \; \; Solve\; for\; x $$

$$ 3x \;=\; 9 $$

$$ x \;=\; 3 $$

After solving the equation we get two points (0,3)

For y intercept x=0

$$ y \;=\; -3x + 9 \; \; Set\; x \;=\; 0 $$

$$ y \;=\; -3(0) + 9\; \; Solve\; for\; y $$

$$ y \;=\; 9 $$

The y-intercept point is (0, 9)

Frequently Ask Questions

What is the y-intercept of a line?

The y-intercept of a line is the point at which the point crosses the y-axis in a cartesian coordinate system. It represents the value of y when the value of x is zero. This point can be directly from the equation of the line.

For a Linear Equation in Slope-Intercept Form: The most common form of a linear equation is the slope-intercept form y = mx + b in which m is the slope of the line and b is the y-intercept.

What is the slope intercept form equation?

The slope-intercept form of a linear equation is expressed as the equation of a line. It is called the gradient on the graph.

$$ y \;=\; mx + b $$

Where,

y is the dependent variable (on the value of x).
x is the independent variable (the value you can choose starting from zero).
m is the gradient of the line to find the slope of the intercept.
b is the y-intercept of the line (the value of y is equal to b as y = b).

The slope-intercept form y = mx + b is a straightforward method that describes a linear relationship between the slope and x and y-intercept values on the graph of the line.

How to calculate x intercepts of a parabola?

The x-intercepts of a parabola, represented by the quadratic equation y = ax² + bx + c, are the points where the graph of the parabola crosses the x-axis. To find these x-intercepts, you need to solve the equation y = 0. Steps to calculate the x-intercepts of a parabola are,

Identify the coefficients a, b, and c from the given set of the quadratic equation to zero: ax² + bx + c = 0.
Calculate the discriminant Δ using the quadratic formula under the square root: Δ = b² − 4ac.
Evaluate the discriminant:

If Δ > 0, then you get the two distinct real roots from the given equation.
If Δ = 0, there is one real root (the parabola touches the x-axis at a single point).
If Δ < 0, there are no real roots (the parabola does not cross the x-axis).

Use the quadratic formula to find the x-intercepts and give points in a solution as (x, 0).

How to calculate y-intercept from two points?

To calculate the y-intercept of a line given two points, you can follow these steps:

Find the slope (m) of the line using the given coordinates of the two points (x¹, y¹)and (x², y²).
Use the slope and one of the points to solve for the y-intercept (b) in the slope-intercept form of a linear equation y = mx + b.

To find the y-intercept from two points:

Calculate the slope m.
The slope of the points is used to solve the y-intercept b value.

The y-intercept is the value of y where the line crosses the y-axis, represented as the point (0, b).

What happens to a line when the y-intercept is changed?

When the y-intercept (b) of a line is changed in the slope-intercept form equation y = mx + b, the line shifts up or down on the cartesian plane without changing its slope. The slope m, which determines the angle or steepness of the line, remains the same.

In this case, each line is parallel to the original line because the slope remains unchanged. The only difference is the vertical position of the line on the graph because the y-intercept b in the slope-intercept form equation y = mx + b results in a shift in the vertical side of the line:
