Three solutions that go with -2x-3y=-7

i need help on this question to find the solution pairs, so that I can graph it on the computer 

Kenneth S.

The teaching of this subject should include these facts:
The graph is a straight line.
You can solve for y, from which you can determine the y-intercept (the b value in y = mx + b)
You can set y = 0, solve for x, and that will be the x-intercept.
Plotting (graphing) a straight line from its two intercepts is usually the best and safest way to graph a line; only when the b value is zero you need to find some point other than the y-intercept.
They (school) should very soon introduce the SLOPE concept.
