A system of two equations has the solution (6, 2). Here is a graph of one of the equations. What could the other equation be?

• y = 4x - 2

• y = (2/3)x - 1

• y = (1/2)x - 1

• y = (-3/2)x + 6

Which system of equations has exactly one solution?

• A.

  y = 3x + 1

  y = -3x + 7

• B.

  y = 3x + 1

  y = 3x + 7

• C.

  y = x + 10

  2y = 2x + 20

• D.

  y = -x + 10

  y = -x + 12

Solve the equation:

3x + 30 + x = 10 + 2x + 5x + 2.

What is the value of x?

• x = 0

• x = 2

• x = 4

• x = 6

• (4, 6)

• (6, 4)

• (8, 3)

• (3, 8)
