Question

1. A(-9,-12), B(-2,2), C(-1,6), D(-5,-2)Slope ofABSlope ofCDLine Typeparallel,perpendicular,or neither

Answer 1

m ab = 2 , m cd =2, Parallel.

1) Given A(-9,-12), B(-2,2) let's find the slope of AB

2) Given C(-1,6), D(-5,-2) let's find the slope of CD

3) Line type

Since the slope determines whether it is parallel, perpendicular, or neither by checking both slopes. As they are identical, we can state that these lines are parallel to each other.
