Question

For the proportional relationship y=−73x, what is the ratio of vertical change to horizontal change? Will the graph of the line increase or decrease? it can have multiple answers like a and d

A.-7/3 The graph increases from left to right.
B. -7/3 The graph decreases from left to right.
C.-3/7 The graph increases from left to right.
D.-3/7 The graph decreases from left to right.

Answer 1

For every 3 x increments to the right, we would decrease the y value by 7. Does that tell you something about the line?

Answer 2

I am assuming that it was supposed to be y=(-7/3)x
