Question

Help, please.

Tell whether x and y are proportional.
X: 2, 4, 6, 8
Y: 5, 10, 15, 20

Answer 1

It’s proportional because as the x values are added the rate of change increases
in the order of +3 +6 +9 +12.

Answer 2

9514 1404 393

Answer:

they are proportional

Explanation:

For x and y to be proportional, their ratio must be a constant.

y/x = 5/2 = 10/4 = 15/6 = 20/8 = 2.5

All the ratios are the same, so x and y are proportional.
