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)
