Which equation represents a porprotional relationship?

D: y=3x basically means for one of x there is three y, you can write it in a 3:1 ratio as well, which you can’t do with the other functions, since they’re not going to have a ratio like that because one’s proportionality is ruined with a constant, one doesn’t change, and one is exponential.

Answer’s D

Hope it helps

You would plot 83 on the 83 line and you would plot -113 on the -113 line.
