Solve each inequality below and graph your solution on a number line.

  1. Change the inequality to an equation and solve the equation. Use the solution(s) to the equation to divide the number line into regions. Test a point in each region to determine if the region is part of the solution or not.

    Number line, with shading between the open points located between 0, & 1, and between 7, & 8.

  1. Refer to part (a).

  1. Divide both sides by before trying to solve the inequality.

    Number line, with shading to the right of the open point, at 5.
