I'm having a hard time with some problems and can't seem to come up with anything that will work. I have a pre-calc final 2 hours, please help!
1. Perform the following operations and reduce to simpliest form: --My answers didn't work out
2. Find all rational zeros using the rational zero test: --Can't remember how to do the rational zero test...
3. Write the equation of a line that is parallel to 2x+3y=6, that passes through the point (1,-1)
4. The vertices of a triangle are located at (1,-1), (1,3), and (4,2). Write the equation for the sides of the triiangle. --Do I use slope and distance or something else?
