If you can plot points, remember that two points determine a line. So, pick two easy points and plot them. Then draw a line through them.
So, what's easy? How about letting x=0 or y=0? That gives us
0-y=5
y = -5
x-0=5
x=5
So, our two points are
(0,-5) and (5,0)
Now it should be clear. You can always pick other points if you want, but they won't really give you any more information.
If you want x=3, then 3-y=5 and y = -2 so the point (3,-2) is on the line too.
