Identify the equation that represents a proportional relationship. а. у=-3x + 2
b. у=-2х +4
c. y= 2x

help me please

c.

Step-by-step explanation:

I'd generally say this would depend on what your definition of proportional is, but there's still one clear answer in this case regardless.

Here, a direct proportional relationship will pass through (0, 0), meaning it will not have a y-intercept and y will be 0 when x is 0.

Because b is the y-intercept, C is the answer as it is the only answer that does not have one.

x/3-10=8

x/3=18

x=48
