slope formulas

Slope (m) = RiseRun

(Rise = change in the y co-ordinate; Run = change in the x co-ordinate)

In the above given graph, the Rise is given for the points B (4,2) and C (4,4) and the Run is given for thepoints A (2,2) and B (4,2)

Rise = change in the y - coordinate = 4-2 =2

Run = change in the x- coordinate = 4-2 =2

Using the slope formula, we get :

Slope( m ) = RiseRun = 22 =1

Slope (m) = [ (y2 - y1)/(x2 - x1)]
