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
•D
•G
•C
•E
•F
•B

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=-4x+2
y=x–8
• Finish working out the
problems.
• Explain how you arrived at your
answer (in at least 2 sentences)
Break @ Bell
• When the bell rings, turn in your
work.
