Question

Select the three equations that pass through the points (–4, –16) and (5, 2):

y + 4 = 2(x – 16)

y – 2 = 2(x – 5)

y = 2x – 8

y + 16 = 2(x + 4)

Answer 1

y − 2 = 2(x − 5), y = 2x − 8, and y + 16 = 2(x + 4)

(These three are all equivalent to y = 2x − 8, which contains (−4, −16) and (5, 2); the first given equation does not.)
