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.
Of course that result can be rigorously obtained, but who cares?

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