GRAPHING SOLUTIONS TO INEQUALITIES ON A NUMBER LINE LESSON 62POWER UP MPAGE 422

INEQUALITIES less than; open circle greater than; open circle less than or equal to; closed circle greater than or equal to; closed circle Open circle: doesn’t include number Closed circle: includes number

EXAMPLES

Alisha has a number in mind. If she adds three to her number the result is less than five. Use this information to write and solve an inequality about Alisha’s number. Then graph the solution set.

EXAMPLES

Jan is participating in a 6 mile run/walk for charity. If she completes the course and runs at least half the distance, then what inequality shows how far she might walk? Graph the inequality.
