Homework Help: Algebra please help!

Posted by Celina on Wednesday, December 10, 2008 at 4:03pm.

I'm very confused with what I'm learning about right now. We are kind of talking about slopes, functions, graphs, etc. Today, my teacher taught about midpoint and distance, and did not explain very well at all. Would someone please explain to me how to find midpoint and distance? I have formulas, but I have no idea how to use them, and when I try them, I get the wrong answer.

Here's one of the questions I must answer:

Use slope to verify that your point from part a (which was line segment PQ, with P being (2, 4) and Q being (-7, -2)) is on the line through P and Q, and use the distance formula to show that your point is just as far from P as it is from Q.

Thank you so much! This homework will be collected tomorrow, so I really need to be able to understand this and apply what you tell me to other problems. Thanks!
