Question

Which equation shows a proportional relationship? *

y= -2x +5
y= 3+ 5x
y= -3x

Answer 1

Answer:

y= -3x

Step-by-step explanation:

The graph of a line with a proportional relationship would have the line go through the origin.

Since the 'y=-3x' equation only shows the slope of the line, it goes through (0,0), or the origin, as it's y-intercept.

y= -3x should be the correct answer.

Hope this helps.
