Question

Find the slope between the two points (12,6) and (20,22)

Answer 1

change in y / change in x

(22 - 6) / (20 - 12)

16 / 8

2

Slope = 2.

Answer 2

The slope of the line between those two points is

(the difference in y-values)
divided by
(the difference in x-values in the same direction).

That's (22-6) / (20-12) = (16/8) = 2 .
