Mathematics
1 answer:
ohaa [14]3 years ago
6 0

Answer:

a and c

Step-by-step explanation:

Find the slope between each pair of points.

a. m = (16 − 10) / (6 − 3) = 2

b. m = (-3 − -12) / (-5 − -8) = 3

c. m = (3 − 4) / (2 − 0) = -1/2

Perpendicular lines have opposite inverse slopes.  So a and c are perpendicular.

also going down from 4 to 8, not including 8, so [4,8)
the union is including both
