Need Help Solving Linear Function?

I am working on an assignment for an online intermediate algebra class. This module is on the rectangular coordinate system, which I know fairly well. However, this one question has me stumped.

Here is the question:

Graph the linear function by plotting the x- and y-intercepts.

-3y = -3x

I've done the x/y intercepts on other questions with no problem, but this one has me confused and there are no similar examples in our lecture or other problems. So far I've tried this;

-3(0) = -3x then solve for x so x = 0/-3 = 0

-3y = -3(0) then solve for y so y = 0/-3 = 0

The answer is multiple choice and has four graphs with (0,0) as the only plot but different slopes. I'm 99.9% certain the slope is irrelevant here.

Have I done this correctly, or did I make a mistake along the way?

Thanks in advance,
