If two points A x₁y₁ and B x₂y₂ lie on the given line such that x₁ x₂ then the slope of the line AB is given as. We will use the formula to calculate the slope of the line passing through the points 38 and -2 10. Substitute the slope for m in the slope intercept form of the equation.
In this lesson students are given the coordinates of two points and are asked to find the slope of the line that passes through the points without graphing.
Y y1 m x x1 We can choose any point on the line for x1 and y1 so lets just use point 23.

Some call the y-coordinates the rise and the x-coordinates the run.
