Question

Find the slope of the line that contains the following pair of points. (4, 8), (8, 11)

Answer 1

you do change in y over change in x so. (11 - 8)/(8-4)

Answer 2

so the slope is 3/4

Answer 3

slope is the average of the two points

to the equation y1-y2/x1-x2 will be used

First, define your two "Y" points (8 and 11) and assign them as y1 and y2 accordingly
Then, define your two "X" points (4 and 8) and assign them as x1 and x2 accordingly

now just plug into your equation:

8-11/4-8
-3/-4
=3/4

3/4 is your slope :P
