   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
