You can put this solution on YOUR website!
Put each of the equations in y = mx + b form
2x + y = -8 becomes y = -2x - 8
-x + y = 4 becomes y = x + 4
Graph each on the same coordinate plane, using the slope and the y-intercept. Where the two lines intersect, that is where the solution is.
If you have a graphing calculator, you can graph them there for the solution as well.
