Multiple Choice

Which system of equations represents the graph of these two lines?

• x - 6y = -90

  x - 3y = 27

• x + 6y = 90

  x + 3y = -27

• 6x - y = -15

  3x - y = 9

• 6x + y = 15

  3x + y = -9

Multiple Choice

Which system of equations is best represented by the graph?

• y = 2/5x - 8

  y = -3/5x - 3

• y = 2/5 x - 3

  y = -3/5 x - 8

• y = 5/2x - 8

  y = -5/3 x - 3

• y = 5/2x - 3

  y = -5/3 x - 8

Multiple Choice

Which system of equations is best represented by lines h and j?

• y = 4/3x - 5

  y = 4/5x + 1

• y = 3/4x - 5

  y = 5/4x + 1

• y = -4/3 x - 5

  y = -4/5x + 1

• y = -3/4x - 5

  y = -5/4x + 1

Multiple Choice

Which graph best represents this system of equations and its solution?

2x = 6 - y

5x - 4y = 28

Multiple Choice

Which system of equations can be used to find b and c?

• b + c = 6.00

  0.08b + 0.15c = 68

• b + c = 68

  0.15b + 0.08c = 6.00

• b + c = 6.00

  0.15b + 0.08c = 68

• b + c = 68

  0.08b + 0.15c = 6.00
