isolate y..best way to graph linear equations is using table of values once you isolated y.

Two great videos on Brightstorm for you to watch are: http://www.brightstorm.com/d/math/s/algebra/u/linear-equations-and-their-graphs/t/how-to-graph-a-line-using-y-equals-mx-plus-band for solving the system:http://www.brightstorm.com/d/math/s/algebra/u/solving-systems-of-equations/t/solving-systems-of-equations-by-graphingAlyssa will show you how to put the equations in y = mx + b form, and how to solve a system of two equations using the graph. Don't forget to watch the concept video and the problems to get a lot of practice with these types of problems.

solve the equation for y, and then us y=mx + b where m is the slope (rise over run) and b is the y intercept of the line
