Answer:

No

Step-by-step explanation:

For x and y to have a proportional relationship, then

the ratio of k = [tex]\frac{y}{x}[/tex] must be equal for all points

(2, 5) → k = [tex]\frac{5}{2}[/tex] = 2.5

(3, 7.5) → k = [tex]\frac{7.5}{3}[/tex] = 2.5

(5, 12.5) → k = [tex]\frac{12.5}{5}[/tex] = 2.5

(18, 8) → k = [tex]\frac{18}{8}[/tex] = 2.25 ≠ 2.5

k is not equal for all values , hence no proportional relationship exists
