Neither. You know that lines are parallel if they have the same slope, and perp, if the slope is the negative inverse. The slope is the inverse, but it is still positive. So neither.

I said it in the reverse order. I'm sorry for the confusion. You SHOULD divide (3 1/2)/(4 3/8), not (4 3/8)/(3 1/2).
October 28, 2008

Your error is that you keep trying to divide (3 1/2)/(4 3/8). When you should do it the other way. (4 3/8)/(3 1/2) You should get 4/5.
