Question

Identify the equation that represents a proportional relationship.

Answer 1

Answer:

c. $y=2x$

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.

$y=mx+b$

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