Here's a Data Sufficiency question from the GMATPrep software that I can't figure out the answer to:
In the x-y plane, does the line with equation y = 3x + 2 contain the point (r,s)?
(1) (3r + 2 - s)(4r +9 - s) = 0
(2) (4r - 6 - s)(3r + 2 - s) = 0
I think each of these statements are sufficient to answer the question, but the answer is supposedly C. Not sure why, so any insights would be greatly appreciated. Thanks!
