Question

A line has a slope of Negative three-fifths. Which ordered pairs could be points on a parallel line? Select two options.

(–8, 8) and (2, 2)
(–5, –1) and (0, 2)
(–3, 6) and (6, –9)
(–2, 1) and (3, –2)
(0, 2) and (5, 5)

Answer 1

Answer: (–8, 8) and (2, 2) and (–2, 1) and (3, –2)

Work: slopes = (2−8)/(2−(−8)) = −6/10 = −3/5, and (−2−1)/(3−(−2)) = −3/5. The others give 3/5 or −5/3.
