Solve the system by graphing

x+y=3

x+y=-1

What I would do is to put the equations in slope intercept form:

y= -x + 3

y= -x -1

Then graph the lines, and see if they cross. If they intersect, that is the solution.

In this case, both lines have the same slope, and are parallel, and never intersect. There is no solution.

Thank you for your help .....
