Answer:
[tex]\frac{2}{5}[/tex]
Step-by-step explanation:
the rate of change is calculated as[tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
where (x₁, y₁ ) and (x₂, y₂ ) are any 2 ordered pairs from the table
using (x₁, y₁ ) = (20, 16 ) and (x₂, y₂ ) = (10, 12 ) , then
rate of change = [tex]\frac{12-16}{10-20}[/tex] = [tex]\frac{-4}{-10}[/tex] = [tex]\frac{4}{10}[/tex] = [tex]\frac{2}{5}[/tex]
