Graphing Lesson
The video below allows you to review how to solve by graphing. Make sure to pay attention to which variables in the equation represent SLOPE and the Y-INTERCEPT.
Graphing Solving
When solving by graphing, it can help to graph both of the equations separately. When you graph the equations, make sure that both equations are in slope - intercept form, or y = mx + b. When graphing, you should be able to tell exactly where they lines intersect, however it can be challenging when they intersect at points that are not whole numbers. To make sure the answers are correct when this happens, it is helpful to double check using an algebraic method. Use the image below to help you set up a graphing problem to successfully show your work.
