Answer:
B
Step-by-step explanation:
The rate of change is a measure of the slope m
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 2, 12) and (x₂, y₂ ) = (0, 3) ← 2 ordered pairs from the table
m = [tex]\frac{3-12}{0-(-2)}[/tex] = [tex]\frac{-9}{0+2}[/tex] = [tex]\frac{-9}{2}[/tex] = - [tex]\frac{9}{2}[/tex]
