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)
