Which equation is parallel to:
y = 5/7x +2

• y = -7/5x +1
• y = 7/5x +4
• y = -5/7x -3
• y = 5/7x +5

Write the equation of the line.

• x = -1

• x = 1

• y = -1

• y = 1

Write the equation of the line.

• y = 5

• x = 5

• x = -5

• y = -5

If a system of equations has no solution, what does the graph look like?

• parallel lines
• skew lines
• intersecting lines

Caitlin won a bag full of money! She has 49 bills in all. She counts $1,430. There are $20 dollar bills and $50 dollar bills. How many of each bill does Caitlin have?
WRITE a system where T= # of $20 and F = # of $50.

• T + F = 1430
  20T + 50F = 49
• T+ F = 49
  10T + 5F = 1430 
• T + F = 49
  20T + 50F  = 1430
• T + F = 49
  T + F = 1430

What is the solution?

• (1, -1)
• (-1, 1)
• (0, -2)
• (2, 0)

What inequality does the number line graph represent?

• x > 4

• x > -4

• x < 4

• x ≥ -4

Write in slope intercept form:

5x - 3y = -9

• y = (5/3)x - 3

• y = (5/3)x + 9

• y = (5/3)x + 3

• y = (3/5)x + 3

Select the correct graph for the inequality.

• A
• B
• C
• D

Solve:

4(5x + 2) ≤ 28

• x ≤ 1

• x ≥ 1

• x ≤ 8

• x ≥ 8
