Test Review Graphing Points Solve Absolute Value Equations Graph equations by plotting points Using equations as Point Testers Find points that satisfy an equation Solve an equation for y (literal solving) Find intersection points Solving equations

Test 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.

Test Review As we go over the topics for the test write down the problems and try to do them. If you do not understand how to do one of the topics, ask for help.

I can graph points Plot these points. A (1,2) B (-4,-8) C (-3,2) D (7,-2) E (7,0) F (0,2) G (0,0)

I can state the coordinates of points that I see on a graph. Write the coordinates. A ( , ) B ( , ) C ( , ) D ( , ) E ( , ) F ( , ) G ( , ) A D G C E F B

I can solve absolute value equations. Solve these absolute value equations -|3| = |-14| = |x| = 2 |2x - 4| = 8 |-2 + 3x| = 10 |x + 3| - 5 = 2 | 7x + 8| + 10 = 0

I can determine if a point is on the graph of an equation Which of the following points are on the graph of the equation 4x + 2y = 20 (4,2) (2,9) (3,4) (1,8)

I can find points that satisfy an equation Find the value of k that satisfies the equation 4x + 2y = 20 (1,k) (4,k) (0,k) (-2,k) (k,0)

I can graph equations by plotting. Graph these equations by plotting y = 2x + 1 x + y = 9 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

I can solve an equation for y. Solve for y x + y = 9 2x + y = 3 4x = y – 3 y – x = -8 4x + 2y = 20

I can find the point where two equations intersect. Find the point where these two equations intersect. y = - 4 x + 2 y = x – 8 Here is another set: y = x2 + 1 y = 3
