How to solve graphically.

[From: ] [author: ] [Date: 11-09-09] [Hit: ]
either using graph paper or your own graph where you are careful about the scale, plot them on the same graph. Check out where they intersect. That point should be your solution. To check, use the x and y values of the point in each of the original equations and see of they are true.......
X=2y and 2x+y=-5 and check by substituting the answer back into the original equations.

Put both equations into point-slope form so that they're easier to graph. Then, either using graph paper or your own graph where you are careful about the scale, plot them on the same graph. Check out where they intersect. That point should be your solution. To check, use the x and y values of the point in each of the original equations and see of they are true.
