Question

(20 POINTS!)

Using the slope formula, find the slope of thenline through the points 0,0 and 4,16.

Answer 1

The slope formula is change in y over change in x

Answer 2

4

Explanation:

Please write 0,0 and 4,16. as points: (0, 0) and (4, 16). As we go from the first to the second point, x increases by 4 and y by 16. Thus, the slope of the line through these two points is

m = rise/run = 16/4 = 4.

This is the same result as

16 - 0

m = ------------ = 4

4 - 0
