I am trying to do some PreCalc homework and I am having problems.. I don't know why, maybe it is just to easy for me to get.. But anyways, here is the problem:
Instructions: Find a number t such that the line passing through the two given points has slope -2.
Problem: (t + 1,5); (6, -3t + 7)
I am really confused, what do I do?

Well, the equation for the slope between two points (x1, y1) and (x2, y2) is Rise/Run or (y2 - y1) / (x2 - x1) = m. So, you have the slope, the two points. Now you can plugin the values and solve for t using simple algebra.
Omfg, thanks for pointing out the obvious. Haha, I'm sorry, I must be having a bad math day. Thanks!
