    Answer: C

    Step-by-step 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.
