Got it right on test

Answer 2

d. y =1/4x

Explanation:

There can be no added constant in an equation expressing a proportional relationship. If the equation is written in standard form (ax+by=c), then the value of c must be zero.

That is, the point (x, y) = (0, 0) must be a solution to the linear equation for a proportional relationship.
