Finding the Slope of a Line from Two Points. Substitute the slope for m in the slope intercept form of the equation. This online Two Point Slope Form Calculator helps you to find the equation of the straight line using the Two Point Form Method.
This online Two Point Slope Form Calculator helps you to find the equation of the straight line using the Two Point Form Method.
The reason being that you will be able to find the slope of a line in the exact same manner as above if you have the values of any two different coordinates on the line. To see how the rise and run relate to the coordinates of the two points lets take another look at the slope of the line between the points 23 2 3 and 76 7 6 below. Substitute either point into the equation. You can also use this method if you are given two points on the line without having the line graphed in front of you.
