same x and y coordinates

The coordinates of the x-intercept are the same as the coordinates of the y-intercept on the graph of which of the following lines?

2x-3y=3
2x+2y=8
2x+y=2
x-3y=0

Re: same x and y coordinates

Hi;

Choose the 4th one.


In mathematics, you don't understand things. You just get used to them.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.

Sorry, misread the question. They want the 4th equation.

Hi;

Did you check what the answer was?
