Question

If a line can be represented by the equation y+2=1/3(x−12), which of the following sets of points lies on the line?

RESPONSES:
A. (12,−2) and (15,−1)

B. (12,−2) and (13,1)

C. (−12,2) and (−11,3)

D. (−12,2) and (−9,3)

Answer 1

Start from the given form y + 2 = (1/3)(x − 12). That is point–slope form with point (12, −2) and slope 1/3, so (12, −2) is on the line. Moving 3 units in x increases y by 1 (slope 1/3), so (15, −1) is also on the line. Thus A is correct.
