Answer:
[tex]-\frac{2}{3}[/tex]
Step-by-step explanation:
If I remember correctly, rate of change is basically slope.
So if you want, you can choose two points and use the slope formula. If you're lazy, or don't necessarily NEED to use the slope formula, then you can just choose two points and count the rise and run.
Slope = [tex]\frac{rise}{run}[/tex]
Rise = -2 (going down two)
Run = 3
Therefore the slope is:
[tex]-\frac{2}{3}[/tex]
