The distance between the y-values of the two points (that is, the height of the triangle) is the "y2 – y1" part of the slope formula. The distance between the x-values (that is, the length of the triangle) is the "x2 – x1" part of the slope formula.

Now that you know how to calculate a slope, you are ready to write the equation. We will use something called the "point-slope" formula. It is called the point-slope formula because you need to know the coordinates of one point and the slope to use it.
