Unformatted text preview: lgfio #- Hole; 3.6 Graphing Linear Inequalities Review: Solving an inequality is the same as solving an equation, except that when you multiply or divide by a negative number, you have to switch the inequality sign around. Example: Solve for y: 3x - 2y > 6 "Ex -'?>x s1 ? 232\$ +Lo ..-2_ ‘2— :5: Graphing a Linear Inequality in Two Variables Solve the inequality for y. Graph the line as you would for an equation. Use a solid line for s or 2: use a dashed line for < or >. If y z shade everything above the line. If y s shade everything below the line. Examples: Graph 3x - 2y > 6 Y4EX“3 Y- To graph the intersection or union of two inequalities: Graph each ineq uality. The intersection is where they ole/ﬂap. The union is the combination of the two graphs. Examples: Graph the intersection of x s 2 and y 2 x + 1 Homework: p. 198 # 1-21 odd (Bonus: 69, 70) .m ...
