Step 1: I'll solve this step by step, following the LaTeX formatting guidelines precisely.. Slope Calculation Formula: Step 2: : Identify coordinates. - $x_{2} = -6, y_{2} = -7$ Step 3: : Calculate slope. Step 4: : Identify coordinates. - $x_{2} = 1, y_{2} = -5$ Step 5: : Calculate slope. Step 6: : Identify coordinates. - $x_{2} = -5, y_{2} = 3$ Step 7: : Calculate slope. Step 8: : Identify coordinates. - $x_{2} = 3, y_{2} = -2$ Step 9: : Calculate slope. Step 10: : Identify coordinates. - $x_{2} = -5, y_{2} = -10$ Step 11: : Calculate slope. UNDEFINED (vertical line) Step 12: : Identify coordinates. - $x_{2} = -4, y_{2} = -2$ Step 13: : Calculate slope. Problem 13: Parallel/Perpendicular Lines Step 14: : Calculate slope of PQ. $m_{PQ} = \frac{-1 - (-4)}{-7 - 9} = \frac{3}{-16} = -\frac{3}{16}$ Step 15: : Calculate slope of RS. $m_{RS} = \frac{-1 - 5}{-6 - (-2)} = \frac{-6}{-4} = \frac{3}{2}$ Step 16: : Determine line relationship. - Parallel lines have equal slopes - Perpendicular lines have negative reciprocal slopes Final Answer: 7. $-\frac{4}{5}$ 8. $1$ 9. $0$ 10. $\frac{3}{4}$ 11. Undefined 12. $-\frac{9}{4}$ 13. Neither parallel nor perpendicular
