Please help me, This is the only question I don’t understand pleas help me I would really appreciate it thank you!

C

Step-by-step explanation:

A proportional equation is in the form:

Where y is the dependent variable, x is the independent variable, and k is the constant of proportionality.

An important aspect of a proportional equation is that it passes through the origin. That is, it has no y-intercept (or a constant value).

From our choices, the only choices that don’t have y-intercepts are C and D.

However, D is not a linear function.

Therefore, our answer is C.

And our constant of proportionality is 1/2.

because they could drop even lower..

answer is x<
