**Part II**

Pick and solve one problem from each group of the following quadratic equations. Try picking problems that have not been chosen and explain what method you used to solve.

Group 1

1. x^2 = 9

2. x^2 -1 = 15

3. x^2 + 4 = 29

Group 2

4. (x + 1)^2 = 4

5. x^2 + 4x + 4 = 25

6. x^2 + 3x = -2

A vertical line and a horizontal line intersect at the point (3,5). What are the equations of the lines?

In order to answer the initial question, you need to know what the equations of a vertical and horizontal line look like. You should have two equations.

1. What is the slope of a horizontal line if it has one? Explain.

2. What is the slope of a vertical line if it has one? Explain.
