whats the graphing method >

2. perl

treat them like lines y = mx + b , make two of them

3. mitosuki

You would put it in y = mx + b form to find the y-intercept and the slope, and so you plot the line. Then plug in a point that is not on the line to see which side is shaded. For graphing use this website: http://my.hrw.com/math06_07/nsmedia/tools/Graph_Calculator/graphCalc.html Note the lines won't show whether it is dotted or a solid line.
