6.5 Linear Inequalities

Remember when...

We graphed inequalities like...

x < 3

Is the ordered pair a solution of the inequality

x + 2y < -3 (-6, 1)

Graph: y > 2x + 8

Graph

y < 3 4 x - 5

Graph x - 5y < 15

You have \$150 to spend on school clothes.

It costs \$20 for a pair of pants and \$15 for a shirt.

Let x represent the number of pants and y represent the number of

Write and graph an inequality that describes the different number

of pants and shirts you can buy.
