4y=5x direct variation or inverse variation or neither constant of variation k =

Usually these equations are written as y = kx so to change this equation into something that looks like y = kx you need to go back to the original question.

4y = 5x Divide by 4

y = (5/4) x

To make y = kx from y = (5/4) x

k must be (5/4)

k = 5/4 <<<<< Answer

a is the right answer

a - base

b - exponent

so,
