on a graph you do rise over run. find a point that falls on an intersecting line and count how many blocks up and over it is to the next point on a line Hope this helped
1. Identify the slope, m. This can be done by calculating the slope between two known points of the line using the slope formula.
2.Find the y-intercept. This can be done by substituting the slope and the coordinates of a point (x, y) on the line in the slope-intercept formula and then solve for b. y=mx+b
