1. A friend is graphing a system of linear inequalities and is confused about how to find the solution region. Explain how to determine the solution region for a system of linear inequalities.
2. Explain which method (graphing, substitution, or elimination) would be most appropriate for solving the given systems of linear equations. Then solve each system using your chosen method.
| a. y = 3x + 5 | b. 9p + + 4q = -17 | c. 5x - 7y = -21 |
| 2y - 6x = 4 | 12q = -3 - 3p | 14y - 5x = 22 |
