4. If line segment AB has coordinates A(-2,4) and B(2,0) and line segment
CD has coordinates C(3,4)and D(-3,-2), how would you describe these two
line segments?

A: neither
B: perpendicular
C: parallel

Answer 1

B

Explanation:

`m_{\overline{AB}}=(4-0)/(-2-2)=-1 \\ \\ m_{\overline{CD}}=(-2-4)/(-3-3)=1`

Since the slopes are negative reciprocals of each other, and since they intersect, they are parallel.
