Answer:
Not proportional
Step-by-step explanation:
If x and y are proportional then the equation relating them is
y = kx ← k is the constant of proportionality
To determine if x and y are in proportion then k must be equal for all ordered pairs, that is
k =
(2, 0) k = = 0
(4, 2) → k = =
(6, 4) → k = =
(8, 6) → k = =
Since k is not constant for all values then not in proportion
