Question

The slope AB is -4

Which segments are parallel to AB?
Select each correct answer.

A. JK, where J is at (8, 2) and K is at (12, 3)
B. CD, where C is at (6, 2) and D is at (4, 10)
C. EF, where E is at (1, 9) and F is at (2, 5)
D. GH, where G is at (1, 0) and H is at (1, 4)

Answer 1

the answer is CD m=y2-y1/x2-x1
m= 10-2/4-6= 8/-2=-4
If 2 segments are parallel they have 2 have same slope
