Point P lies in which quadrant?

• Quadrant 1

• Quadrant 2

• Quadrant 3

• Quadrant 4

A co-ordinate that represents a point that lies on the x-axis is?

• (0, 4)

The height and capacity of five cooking containers are shown on this graph.

The shortest container is the:

• Oven tray

• Measuring jug

• Cup

• Saucepan

The gradient of the line shown below is:

• Undefined

• Negative

• Positive

• Zero

An electrician charges $120 for a callout and then $20 per hour of work.

If C represents the total cost in dollars and t represents the time the electrician works in hours, the rule for the cost in terms of the time taken for the job is C = 20t + 120

If the electrician worked for 1.5 hours, the cost would be:

• $150

• $140

• $160

• $250

The y-intercept of the line with equation y = -3x + 3 is:

• -3

• 0

• 3

• 6

Two lines are parallel if:

• The y – intercepts are the same

• The x – intercepts are the same

• The gradients are different

• The gradients are the same

If the gradient of a line is -2 and the y-intercept is 4, then the equation of the line is:

• y = 4

• y = -2x + 4

• y = -2x - 4

• y = 4x -2

What are the coordinates of C?

• (-4, 5)

• (4, 3)

• (5, -4)

• (1, -3)

What is the gradient of the graph shown?

• 0

• 4

• 3

• 1
