Question

Which Equation represents a Non-Proportional relationship between X and Y?

A. y=x

B. y=7x

C. y= 2/3x -1

D. y=3x + 0

Answer 1

Answer: C

Explanation:

proportional relationship will have an equation that goes through the origin (0,0)

The equation for C will not go through the origin because it has a y-intercept of -1 and the line will be going through (0,-1) instead of (0,0).

All the other equations will be going through the origin because they have no y intercepts.
