slope m
= rise / run
= 7.6 / 9
= 0.8

(-9, -4)

(0, 3.6)

(0, -4)

y2 - y1
= 3.6 - -4
= 7.6

x2 - x1
= 0 - -9
= 9

Click the A or B point and drag to change.

You can move the graph up-down, left-right if you hold down the "Shift" key and then drag the graph.

Find the slope of the line joining the points (-9, -4) and (1, 3).

So the slope is: 0.7
