1. What is the mid point of the line (1, 9) (5, 15)

   • (1, 15)
   • (3, 12)
   • (6, 24)

2. On a distance-time graph what does a line segment that is horizontal tell you?

   • The data is incorrect
   • The distance travelled was slowing down
   • The distance travelled was speeding up
   • There was no movement during the period

3. Which of these equations would give the steepest gradient?

   • y = x

   • y = 3x - 1
   • y = 4x - 1
   • y = 5x - 1
   • y = 6x -1

6. If a graph equation contains only the signs of plus, minus and equals then what could you definitely say about the line?

   • It is very long
   • It is very short
   • It is straight
   • It is curved

7. If a graph equation contains an exponent then what could you definitely say about the line?

   • It is very long
   • It is very short
   • It is straight
   • It is curved

8. Two coordinates of a line are as follows: (3, 12) and (2, 8). What is the equation?

   • y = 2x
   • y = 4x
   • y = 6x
   • y = 8x

9. Two coordinates of a line are as follows: (3, 21) and (2, 14). How might the line best be described?
