Question

The value of y varies directly with x. Which function represents the relationship between x and y if y=20/3 when x=30

Answer 1

y=254x

Explanation:

y=254x

Answer 2

Set it up as a direct variation: y/x=k, where k is the constant of variation. (20/3)/30=k gives us a k value of 8/9. The function would be y=8/9x
