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)
