Quizplus · Accepted Answer

By graphing, we can see that the two lines intersect at the point (0, 0) which satisfies both equations. Therefore, the answer is not D. Additionally, the lines have different slopes, so they cannot be parallel and they must intersect at some point. Therefore, the answer is not B or C. This leaves only A as the possible answer.
