Part 1
1. Use the Microsoft® Excel graphing tool to graph the inequalities. Shade the area that represents the solution to the each inequality.

1) y &#8805; 5x + 2

2) y < -3x + 1

3) 2x - 6y &#8804; 18

Use the Microsoft® Excel graphing tool to graph the systems of inequalities. Shade only the area that represents the solution to the each system.

4) y &#8804; 3x + 4
y &#8805; x + 2

5) y &#8804; 2x - 5
y &#8805; 2x + 3

6) y &#8804; 4
y &#8805; 5x - 6
y &#8805; -4x + 4

Part 2
For problems 1-3 solve each equation for x by graphing. Write your answers as an ordered pair (x,y). Show your work and check your answers.

1) 4x2 = 20

2) x2 + x - 12 = 0

3) (x + 2)2 + 4 = 0

4) Use the graph to find the zeros of y = -x2 + 9.

5) Explain how to find the solutions to the equation (x + 4)(x - 1) = 0.
6) Find the solutions for x. Show your work and check your answer.
(4x - 3)(2x + 6) = 0

7) Solve the quadratic equation x2 + 6x + 5 = 0 by factoring. Show your work and check your answer.

8) Solve the quadratic equation 2x2 + 7x + 5 = 0 by factoring. Show your work and check your answer.
