10. Graph Each Line On your graph paper: 1. 2. 3. y – 3 = –2(x + 4) 4.

11. Slopes of lines and graphs of lines

12. Systems of lines
Graph each set of lines and decide if they are parallel, perpendicular, intersect, or coincide. 2. 3. 4.
1. y = 3x + 7, y = –3x – 4
3x + 5y = 2, 3x + 6 = -5y
2y = 4x + 12, 4x – 2y = 8
