Suppose y varies directly with x. Write a direct variation equation that relates x and y.

Y=-10 when x=2

A. Y=-5x

B. Y = - 1/5x

C. Y=5x

D = Y=1/5x

If y varies directly with x, then whatever is done to y is also done to x, and vice versa.

All of the answers relate to when the value of y is positive 1, meaning we have divided the original y by - 10.

We must also do this to x, as they are directly proportionate, meaning x = 2 now becomes x = - 1/5

Therefore the answer is [B]
