What is this coordinate?
- $(2,-5)$
- $(-2,-5)$
- $(5,-2)$
- $(-2,5)$ ✓
What's wrong with the labelling of this coordinate?
- The signs are the wrong way round on both coordinates. It should read $(3,-4)$ ✓
- It's below the $x$ -axis so both need to be negative. $(-3,-4)$
- Nothing. That is the coordinate $(-3,4)$
The sides of this rectangle are parallel to the $x$ and $y$ axes. What is the missing fourth coordinate?
- $(-11,-12)$
- $(-12,-10)$
- $(-12,-11)$
- $(-12,-9)$ ✓
- $(-9,-12)$

That coordinates only exist, and can only be plotted, on the lines of graph paper.

Between any two vertices there are infinitely more points. Ask pupils to consider what numbers are between 1 and 2.
