An equation to be graphed must be written (or must be entered in a graphing calculator) in the form y = ..., that is, y must be expressed as a function of x.

After a graph is displayed in your graphing calculator, you can use the calculator's TRACE feature to find the x-intercept(s) (a point that the graph intersects the x-axis where y = 0).

Move the TRACE cursor to a point just below the x-axis and press ENTER, MOVE the TRACE cursor to a point just above the x-axis and press ENTER, press ENTER again. In this way you can find the x-intercept(s).

Thus, each x-intercept of the function is a real solution of the equation to any desired degree of accuracy.

By graphing the lines on the coordinated plane they will intersect at (2, -4) which is the solution of the equations

Substitution is a way to solve without graphing, and sometimes there are equations that are impossible or very difficult to graph that are easier to just substitute. Mostly though, it is a way to solve if you have no calculator or cannot use one (for a test or worksheet).

This looks like a question from a Virtual School course - please ask you teacher for help and use the examples in the lesson.

A graph can help you understand equations better its a little way of getting used to a a problem. I used a multiplication graph when i was 10 it helped me memorize the problem.

-- Graph each equation individually. -- Examine the graph to find points where the individual graphs intersect. -- The points where the individual graphs intersect are the solutions of the system of equations.
