## Introduction to Slope Calculator:

Slope calculator is a digital tool specially designed to **evaluate the slope** of a given line in seconds. It helps you find the straight line equation from the cartesian coordinates that pass through that line.

Our slope of a line solver can easily be found on online platforms, on your computer, mobile device, or laptop. You need to add the input values, and it immediately provides a solution in the form of the slope of the line.

## What is Slope?

The slope of a line is the **measurement of the steepness** and direction of an inclined object. In a Cartesian coordinate system, the slope is defined as the ratio of the vertical change (called rise) and the horizontal change (called run) between two points on the line.

Slope plays a crucial role in interpreting and analyzing linear relationships on a graph. It helps to understand the various concepts of scientific study, as in math, it is used to know the properties of linear equations and graphs, or in physics, velocity, or time graphs.

Need to calculate the slope efficiently between two points? Our slope of a line calculator simplifies the process, delivering accurate results in no time.

## What is the Slope Formula?

The **slope formula for a line** between two points (x1,y1) and (x2,y2) on a Cartesian plane is:

$$ m \;=\; \frac{(y_2 - y_1)}{(x_2 - x_1)} $$

$$ m \;=\; \frac{rise}{run} \;=\; \frac{\nabla y}{\nabla x} \;=\; \frac{y_2 - y_1}{x_2 - x_1} $$

The slope formula, often denoted by 'm', represents the ratio of the vertical change (rise) to the horizontal change (run) between two points on a line. When you need to find the slope between two given points, many people use a slope formula calculator to speed up the process.

Whereas,

- m is the slope.
- (x1, y1) are the coordinates of P1.
- (x2, y2) are the coordinates of P2.
- y2-y1 is the vertical change or the rise of line
- x2−x1 is the horizontal change or the run of the line.

## How to Calculate the Slope of a line?

To calculate slope of a line between two points, you must have well-versed knowledge about graphs and their core concepts. Nevertheless, here, you get a complete understanding of the **slope of a line method** in a stepwise process, so you will quickly get a hold of the slope of a line method. These steps are:

**Step 1**: First, determine the coordinates of (x,y) of two points as (x1,y1) and (x2,y2).

**Step 2**: Then, use the slope formula and put the point values in it.

$$ m \;=\; y_2 − \frac{y_1}{x_2 − x_1} $$

Here, y2 - y1 is called rise or vertical change on the line, and x2 - x1 is called run or horizontal change on the line. To determine the rise over run, the following formula is used,

$$ m \;=\; \frac{rise}{run} $$

**Step 3**: After subtraction, you get the slope of a line and a solution in the form of a fraction.

**Step 4**: It has some special cases as well:

**Horizontal Line**:

If the y-coordinates are the same as y1 = y2, then the slope is m = 0 because,

$$ m \;=\; \frac{y_1 - y_2 }{x_2 − x_1} $$

$$ m \;=\; 0 $$

**Vertical Line**:

Suppose the **x-coordinates are the same** as x1 = x2. In that case, the slope is undefined because it involves a value that is divided by zero as:

$$ m \;=\; \frac{y_2 − y_1}{ x_2 - x_1} $$

$$ m \;=\; y_2 \;=\; \frac{y_1}{0} $$

$$ m \;=\; undefine $$

**Positive Slope**:

If both the points are increasing as y2 > y1 and x2 > x1, then the **slope is positive**, which shows a line rising from left to right.

$$ m \;=\; \frac{y_2 - y_1}{x_2 - x_1} $$

$$ m \;=\; positive\; term $$

**Negative Slope**:

If y2 < y1 and x2 > x1, the slope is negative, indicating the **line falls from left to right**.

$$ m \;=\; \frac{y_2 − y_1}{x_2 - x_1} $$

$$ m \;=\; negative\; term $$

**Step 5:**

It is necessary to double-check your calculations to avoid any mistake if the given point has negative values. If you follow these steps, you can get a precise solution of the slope of a line from the given on that line.

## Solved Example of Slope:

Let’s understand the how to find slope of a line with the help of given example.

### Example: Find the slope of the line given two points

$$ P_1 \;=\; (-2, -3) \;and\; P_2 \;=\; (-7, 4) $$

**Solution:**

Identify x1,y1 and x2 ,y2 points from a line,

$$ x_1 \;=\; -2,\; y_1 \;=\; -3 $$

$$ x_2 \;=\; -7,\; y_2 \;=\; 4 $$

Slope formula is:

$$ m \;=\; \frac{y_2 - y_1}{x_2 - x_1} $$

Put x1,x2 and y1,y2 value in the slope formula

$$ m \;=\; \frac{4 - (-3)}{-7 - (-2)} $$

$$ m \;=\; \frac{7}{-5} $$

$$ m \;=\; -\frac{7}{5} $$

Therefore the slope of the given line is

$$ m \;=\; -\frac{7}{5} $$
