1. Haley solving the inequality -132r + 7 means she is looking for the values of 'r' that make the inequality true.
2. When graphing the solution on a number line, a solid circle represents a closed point (included in the solution), while an arrow pointing left indicates that the solution extends to the left infinitely.
3. In this case, if Haley placed a solid circle at -20 and drew an arrow pointing left, it implies that the solution includes -20 and all numbers to the left of -20.
4. Therefore, if the inequality was correctly solved as -132r ≤ 7, then Haley's graph with a solid circle at -20 and an arrow pointing left would be correct.
5. However, if the inequality was solved incorrectly, and the correct inequality is -132r + 7 < 0, then the graph should have an open circle at -20 (since it's not included) and an arrow pointing left to represent all values less than -20.
In conclusion, whether Haley is correct or not depends on how she solved the inequality. If she solved it accurately, her graph is correct. If not, the graph should be adjusted to match the correct solution.
