A line contains the points (0, -1) and (-1, 2). Another line graphed in the same coordinate plane contains the points (2,0) and (-2,3).
Based on the slope of these lines, are they parallel, perpendicular or neither?

I picked neither??/

Let's see. $$m_1 = {2 +1 \over -1 - 0}  = {-3 \over 1} = -3~\text{and}~ m_2 = {3 - 0 \over -2 - 2} = {3 \over -4} = {-3 \over 4}$$It would seem your answer is correct.
