The ordered pairs (20, -29.5), (21, -31), and (22, -32.5) are points on the graph of a linear equation. Which of the following graphs shows all of the ordered pairs in the solution set of this linear equation?

• 
• 
• 
• 

Solve for x:
4(x + 3) – 6(x + 3) = 2x + 10

• x = -4
• x = 4
• x = 7
• x = -7

Factor completely: 
3x² + 18x +15
Hint: Factor GCF first.

• 3(x² + 6x + 5)
• (x + 5)(x + 1)
• 3(x + 5)(x + 1)
• Prime

Find the Error
What error did the student make when solving the equation:
1/5x + 6 = 3/5x + 5
1x + 6 = 3x + 5
-2x + 6 = 5
-2x = -1
x = 1/2

• The student found an incorrect common denominator
• The student did not multiply all terms by the common denominator
• The student did not use opposite operations appropriately
• The student did not correctly eliminate the variable from one side of the equation

Steffen graphed two lines in order to find the solution to a given system of equations.
What is the solution?

• (-3,-8)
• (-8,-3)
• (3,-8)
• (8,3)

4x - 2y = 7
 x + 2y = 3
What are x and y?

• x = 2, y = 2
• x = 1/2, y = 2
• x = 2, y = 1/2
• x = 2, y = -2
