Khan Academy: Solving by Graphing

Draw graphs to find the common point (Skill #2)

Use the points to reposition the lines to the equations given, then enter in the value of x and of y that satisfies both equations. You may use the check box to find out the equations of the lines you have drawn. Usually there is one unique solution, but from time to time there are infinitely many possibilities.
