a. y = - 2/3 x +2

b. y = 2/3 x + 2

c. y =

Answer 1

Answer: Choice B and choice D

----------------------------------------------

Parallel lines have equal slopes. Each answer choice is in the form y = mx+b which is slope intercept form. For choices B and D, we see the slope is m = 2/3. This is why these lines are parallel. The other choices have different slopes (m = -2/3 for choice A; m = 3/2 for choice C)
