Ch 3 Review I can graph points (x,y). I can state the coordinates of points that I see on a graph. I can solve Absolute Value Equations I can graph equations by plotting points I can determine if a point is on the graph of an equation I can find points that satisfy an equation I can solve an equation for y (make it y = _____) I can find the point where to equations intersect.

Chapter 3 Review Write down each problem. Solve the problem and explain in at least 2 complete sentences how you arrived at your answer. I will keep each question on the screen for 2 minutes. Write them all down.

1. Plot these points A (1,2) B (-4,-8) C (7,-2) D (7,0) E (0,0)

2. Write the coordinates of the following points. A (, ) B (, ) C (, ) D (, ) E (, ) B A D C G F E

3. Solve the absolute value equation for x |2x - 4| = 8

4. Which of the following points are on the graph of the equation? 4x + 2y = 20 (4,2) (2,9) (3,4) (1,8)

5. For each ordered pair, find the value of k that satisfies the equation 4x + 2y = 20 (0,k) (k,0)

6. Make a table and graph the equation 4x = y – 3 Remember the steps 1. Make a Table for your points 2. Choose values for x 3. Plug the x values into the equation and solve for y 4. List your points in your table 5. Plot your points 6. Connect the points

7. Solve for y 4x = y – 3

8. Find the point where these two equations intersect. y = - 4 x + 2 y = x – 8

Finish working out the problems. Explain how you arrived at your answer (in at least 2 sentences)
