- number
- coordinate ✓
- vector
On a coordinate grid the vertical axis is labelled as ...
- $x$
- $y$ ✓
- $z$
What is this coordinate?

What's wrong with the labelling of this coordinate?
- We use dots, not crosses to mark coordinates.
- There is no comma between the $x$ and $y$ coordinates. ✓
- The $x$ and the $y$ coordinates are the wrong way round.
- Nothing.
The coordinate $(0, 0)$ is also known as ...
- point zero
- the origin ✓
- the start
- the nil coordinate

Which language best describes this coordinate position?
- 2 along, 5 up
- 2 right, 5 up
- 2 in the $x$ direction, 5 in the $y$ direction
- 2 in the positive $x$ direction, 5 in the positive $y$ direction ✓

It is possible to plot coordinates approximately in the correct quadrant.
Coordinates can be plotted exactly when the axes are labelled.
By careful consideration of coordinates the missing vertices of a shape can be found.

Where is coordinate (−2,5)? 2 down, 5 right from the origin? 5 right, 2 down from the origin?

Coordinates in (x,y) form. −2 is x-instruction. From (0,0) will we travel in a positive or negative x-direction?

Quadrant - Any one of the four areas into which a space is divided by the x- and y-axes in the Cartesian coordinate system.
