The question, in short

Grid question: read off point A's coordinates, plot and label point B at (4, −2), and give the equation of line CD.

Summarised in our own words. Use the official paper for the exact wording and the diagram.

Part (a) · 1 mark

State the coordinates of point A from the grid.

  1. 1Read the coordinates of point A from the grid.
  2. 2x-coordinate is −2, y-coordinate is 3.
  3. 3(−2, 3)

Answer(−2, 3)

Part (b) · 1 mark

Plot point B at (4, −2) on the grid with a cross and label it B.

  1. 1Locate x = 4 on the x-axis.
  2. 2Move down to y = −2.
  3. 3Mark the point with a cross at (4, −2).

Answer(×) at (4, −2)

Part (c) · 1 mark

Give an equation for the line CD shown on the grid.

  1. 1Observe that line CD is horizontal.
  2. 2Identify the y-value where CD crosses the y-axis.
  3. 3All points on CD have y = −3.
  4. 4y = −3

Answery = −3
