## Formula of Line Equation from Two Points:

The **formula of the equation** of line with two points consists of a slope of m that is found from the given two distinct points (x_1,y_1) and (x_2,y_2). The formula of equation of a line with two points used by line equation from two points calculator 3d is,

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

## How to Calculate Line Equation from Two Points?

For the **calculation of the equation** of line with two points, the line equation calculator from points follows some basic rules for solving the equations. Here is the guide for finding the line equation in different forms from point-slope form to standard form.

**Step 1**:

Identify the two given points be (x1, y1) and (x2, y2).

**Step 2**:

To Calculate the Slope m of the line use the formula of slope of the line which is given as,

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

**Step 3**:

Put the value in the above equation to get the value of slope m to find an equation of a line with two points.

**Step 4**:

For the equation of a straight line use the Point-Slope Form formula which is given as:

$$ y - y_1 \;=\; m(x - x_1) $$

**Step 5**:

Add the value of slope m and the given points (x_1, y_1) into the point-slope form.

**Step 6**:

Simplify the above algebraic expression (if needed) to convert the line equation into a standard form that is given as,

$$ Ax + By \;=\; C $$

## Solved example of Line Equation from Two Points:

The line equation from two points calculator with steps can find equation of line with two points easily but its essential for you to understand the step by step calculation process. So, an **example** is given below,

### Example: Find an equation of a line with two points (-3, -1) and (2, -2)

**Solution**:

The given points (x1,y1) and (x2,y2) is,

$$ points\; (-3, -1)\;and\; (2, -2) $$

The equation of line for two points is,

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

Put these points value in the above formula to find the value of m,

$$ m \;=\; \frac{-2 - (-1)}{2 - (-3)} $$

Solve it to get the value of m,

$$ m \;=\; \frac{-1}{5} $$

For the equation of the line that pass through between these points is,

$$ y - y_1 \;=\; m(x - x_1) $$

Put the value of x1 and y1 from the given equation (you can take other point as x1 and y1),

$$ x_1 \;=\; -3\; and\; y_1 \;=\; -1 $$

$$ y - (-1) \;=\; -\frac{1}{5} (x - (-3) $$

$$ y + 1 \;=\; -\frac{1}{5}(x + 3) $$

$$ y + 1 \;=\; -\frac{1}{5} x - \frac{3}{5} $$

$$ y \;=\; -\frac{1}{5}x - \frac{3}{5} -1 $$

After solving you get the solution of equation of line from two points,

$$ y \;=\; -\frac{1}{5}x - \frac{8}{5} $$
