Answer:

  A.  the y-intercept is positive

  D.  the y-intercept is negative

Step-by-step explanation:

A proportional relationship is characterized by the equation ...

  y = kx

The y-intercept of this equation is zero--the line intersects the origin.

If the y-intercept is not zero (is positive or negative), then the relation is nonproportional.
