Which does not show a direct variation between X & Y?

A. Y = 5X

B. Y = 6/X

C. Y = 0.7X

D. Y = X/9

Answer 1

A direct variation has a constant ratio - generally in the form a*x. 3 of these are under that form. Which one is not?

Answer 2

In other words - it is a direct variation if y/x = a. but x MUST be the denominator.

For example, the direct variation factor of a would be 5, because y/x will ALWAYS be 5.

Answer 3

Oh okay

Answer 4

So would the answer be A?

Answer 5

Answer 6

you want the one that does NOT show direct variation. A shows direct variation.

Answer 7

Look for the one that doesn't have a constant value for y/x
