Does the table represent a proportional relationship if so, write the equation? x 1 y 5, x 2 y 9 x 4 y 17 x 7 y 29 x 9 y 37 will give braniest so confused

The relationship is not proportional.
The equation is:
Y = 4x + 1
When x doubles from 1 to 2, or from 2 to 4, y does not double, so x and y are not proportional.
