1. Pre Calc Review

2.  Appendix B-2 ◦ Plot points on a graph ◦ Find x and y intercepts  X intercepts (, 0)  Y intercepts ( 0, ) ◦ Graph equations with a calculator and determine the proper window ◦ Use the zoom and trace features on a calculator

3.  Determine whether the following are solutions to the given equation: Equation: y = 10x – 7 Possible solutions:(2, 13) (-1, -3)

4. x-2012 y Using your calculator, graph the following equation: From the graph, complete the table of values:

6.  Page A43: Match the graphs to the equations for problems 11 – 16 For the next problems, make sure your window is set to standard viewing (-10, 10, 1, -10, 10, 1, 1)  Page A44: Follow directions for problems 47, 48

7.  How do you eliminate fractions in an equation?  ALWAYS check your solution!!!

8.  Appendix B-3 ◦ Solve linear equations ◦ Set up models to solve problems ◦ Translate key words and phrases to equations ◦ Use various formulas  Perimeter, area, volume, simple interest, compound interest, distance, temperature ◦ Solve word problems

9.  Try this one:  Hint: find the LCD

10.  How do you eliminate decimals in an equation?

11.  Remember there must be 2 cases ~ a positive and a negative.

12.  Find the intercepts for : 2x + 3y = 5  What do we know about ALL y intercepts?  What do we know about ALL x intercepts?

13.  Look at page A54 at the different types of equations.  What are the four ways to solve a quadratic equation? (review page A54)

14.  By factoring:  By the square root property:

18.  Isolate the radical  Square both sides  Linear or Quadratic? ◦ Solve depending upon what type of equation  OR if still a radical present ~ start over at the top
