Answer:

y = 5x

Step-by-step explanation:

The equation for direct variation is y = kx, where k is the factor of variation. So we know that y and x must fit into this formula.

They've given us a y and x value to solve for k.

y = kx

15 = 3k

15/3 = k

k = 5

Plug k back into our equation.

y = 5x

5x=y

5(3)=15

15=15
