Expert Solution

Step 1

Since you have asked multiple question, we will solve the first question for you. If you want any specific question to be solved then please specify the question number or post only that question.

We have

A(-9,-12), B(-2,2), C(-1,6), D(-5,-2)

For slope of AB: A(-9,-12), B(-2,2)

$\Rightarrow m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}} \Rightarrow m = \frac{2 - (- 12)}{- 2 - (- 9)} = \frac{2 + 12}{- 2 + 9} \Rightarrow m = \frac{14}{7} = 2 \Rightarrow m = 2$

Hence, the slope of AB=2
