Answer:
-0.2
Step-by-step explanation:
Between the left marked point and the right one, the y-value changes by ...
Δy = 2 -3.6 = -1.6
and the x-value changes by ...
Δx = 5 -(-3) = 8
The rate of change of y with respect to x is the ratio of these:
Δy/Δx = -1.6/8 = -0.2
The rate of change of y with respect to x is -0.2.
