This week in pre-calc we learned a new way to graph quadratics and linear equations using one and two variables. If it only has 1 variable that means you can only graph along the x-axis. If it has 2 variables you can use both x and y. To start you must first faxtor the equation, then you have to graph it. Once you’ve graphed it you have to decide whether it has a dotted or solid line. If its solid that means < or equal to and > or equal to. If it has a dotted line it mean < or >. Next you have to shade the proper side by choosing a test point. The best point to choose is (0,0).

This is an example of a 2 variable equation graphed.
