If you are stuck on basic graphing techniques and you are not familiar or comfortable with the slope-intercept form of graphing, then simply make an x/y table for each equation and graph the points on from your table onto a graph paper, both tables/graphs on one chart.  Where the lines intersect on your graph paper is the solution of the system  For example,

well an easy method if use a table of values or the intercepts... 

which suits you better
