The quantities x and y are proportional.

Answer:
r = 1
Step-by-step explanation:
Given the equation of proportion
y = rx ← r is the constant of proportionality
Divide both sides by x
[tex]\frac{y}{x}[/tex] = r
Choose any ordered pair from the table
Using x = 5.8 and y = 5.8 , then
r = [tex]\frac{5.8}{5.8}[/tex] = 1
