Warm Up 4/30

Warm Up Problems:
1. The slope of a line is -3, the point (0,-2) is on the line.  What is the equation of the line?

2. These three points are on the same line: (-3,0), (-1,1), (1,2).  What is the equation of the line?
[embed graph here from google doc with g(math) add on?]
3. Factor this expression:  2x^2 - 7x + 3

4. 4(3x+1) - 4 < 4x -8

5. Solve this system:  2x + y = 14
                                 x        = -y + 7
