    __________________________________

    Question 2 and 3 refer to the following graph.

  2. What is the equation of line A?
    • y - 4x = 3
    • y - 1/4x = -2
    • y + 1/4x = -2
    • y + 1/4x = 3
  3. What is the equation of line B?
    • y = -x
    • y = x
    • y = 2x
    • y = -2x

    Questions 5 and 6 refer to the following graph.

  5. What would be the equation of a line drawn through points P and Q?
    • y = -x + 3
    • y = -x -3
    • y = 3x + 2
    • y = 3x + 3
  6. What would be the equation of a line drawn through points R and Q?
    • y = 1/2x - 2
    • y = 1/2x - 3
    • y = 2/3x -2
    • y = 2/3x -3
Answers:

  1. y = 3x - 5
  2. y + 1/4x = 3
  3. y = x
  4. Slope = 5, y-intercept = (0, -1)
  5. y = -x + 3
  6. y = 2/3x -2
