Answer:
Slope =

Explanation:
Let's take two points on the line graphed for a function.
Slope of this linear function =

Between two points chosen,
Rise = Vertical distance on y-axis (Increase or decrease) from one point to the second
Run = Horizontal distance on x-axis from one point to second
Let the points on the graph are (-8, 0) and (0, 4).
Rise = 4
Run = 8
Therefore, slope of the line =
=

Slope =
