  2. Graphing More than One Inequality • Steps • Solve for y in each equation • Do not forget the rules for solving inequalities • Sign changes direction when multiplying/dividing by a negative number • Sign changes direction if you swap sides of the variable and final answer • Graph each inequality • Shade areas that satisfy BOTH inequalities • Shading is in the same area(s) www.themegallery.com
