Question

The value of y varies directly as x, with a constant of variation of -8. What is the value of y when x is 7?

Answer 1

-56

Explanation:

y = kx,

Where k = -8

y = -8x

y = -8(7)

y = -56

Answer 2

y = -56

Explanation:

The equation for direct variation is

y = kx where k is the constant of variation

y = -8 x

We know x =7

y = -8*7

y = -56
