What is the slope of (5,8) (5,10)

Use the slope formula: m - (y2 - y1) (x2 - x1). do NOT multiply them. just subtract inside the (). m = (10 - 8) (5 - 5) m now equals: (2,0) that is your slope.

Your slope will be 0 because you will take one y value minus the other and get 2 - - > 10-8=2. Then you will take the x-values in and subtract them in the same orders as the y-values and get 0 - - > 5-5=0. Slope is rise (y) over run (x) so your slope would usually be your y/x but your slope can not be 2/0 because 2 parts of nothing is nothing so your slope will end up being 0.
