2. Lesson 5.6 WarmUp:
Solve each inequality.
1) ­2x + 4 > ­6
2) 5n ­ 3(n ­ 6) > 0
3) 23 ­ t < 2(t ­ 9) ­ 3(t + 2)
Solve each compound inequality. Then graph the solution.
4) m + 3 > 5 and m + 3 < 7
5) ­n > 2 or 2n ­ 3 > 5

3. Lesson 5.6:
*linear inequality ­ an inequality with 2 variables (x and y) that include a
"half­plane" of the coordinate graph.
*Steps for graphing a linear inequality:
­­Graph the inequality (as if it were an equation)
[Use a dashed line for < or > and a solid line for < or >.]
­­Pick a point and "test" it in the inequality.
­­"IF the point works...shade the half­plane containing the point
and "IF" the point doesn't work...shade the other half­plane.
