A collection of 84 linear inequality problems for practice. Students are asked to solve each inequality by giving their answer as an inequality in interval notation and graph the solution set. A wide range of linear inequalities, including those with constants, variables, and coefficients with both positive and negative signs.

Solve each inequality giving your answer as an inequality, in interval notation, and graph the solution set. Do not
use a calculator. Work the odd problems, if you have any trouble whatsoever also do the even problems. The last
12 problems are review problems.
