Answer:
[tex]\frac{1}{4}[/tex]
Step-by-step explanation:
rate of change is a measure of the slope.
Calculate slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (9, - 29) and (x₂, y₂ ) = (13, - 28)
m = [tex]\frac{-28-(-29)}{13-9}[/tex] = [tex]\frac{-28+29}{4}[/tex] = [tex]\frac{1}{4}[/tex] ← rate of change
