Directions: Grab paper, pencil, and a stratight-edge. You may also want a sheet of graph paper. Use your graphing calculator only for checking your results. Beware!! The cartoon assistants may, or may not, be helpful!

 1. Solve and check this system algebraically:         y = x2 - x - 6      y = x - 3

 2. Solve and check this system algebraically:          2x + y = 2       y = (x - 1)2 + 1

 3. Solve and check this system by graphing:         y = x + 3      y = x2 - 2x - 1

 4. Solve and check this system by graphing:              y = -x2 - 2x + 8           2x - y = -3
