Homework Help: Calculus:Help!

Posted by Derek on Thursday, July 3, 2008 at 6:14pm.

Any ideas on how to solve this: Use a vector solution to show that a scalar equation for the line through the points P1(x1, y1) and P2(x2, y2) is  y-y1/x-x1 = y2-y1/x2-x1? Very confused as to what is meant by this question. Thanks.
