Answer:
No
Step-by-step explanation:
For x and y to have a proportional relationship, then
the ratio of k =
must be equal for all points
(2, 5) → k =
= 2.5
(3, 7.5) → k =
= 2.5
(5, 12.5) → k =
= 2.5
(18, 8) → k =
= 2.25 ≠ 2.5
k is not equal for all values , hence no proportional relationship exists
Division property of equality
