 Linear Quadratic Systems (line-circle) Terms of Use    Contact Person: Donna Roberts  Directions: Grab paper, pencil, and a stratight-edge. You may also want a sheet of graph paper. Beware!! The posed pictures may, or may not, be helpful in solving the problems!
 1. Solve and check this system algebraically:         x2 + y2 = 9      y = 2x - 3 2. Solve and check this system algebraically:          (x + 1)2 + (y - 1)2 = 18        y = x - 4 3. Solve and check this system by graphing:         (x - 2)2 + (y - 1)2 = 4        x + y = 1 4. Solve and check this system by graphing:              x2 + y2 = 4           y + 4 = -x 5.
