Firstly, we recap the concept of ( x, y ) coordinates, illustrated in the following examples.
On a set of coordinate axes, plot the points
A (2, 3), B (0, 4), C (–2, 3), D (–1, –2), E (–3, 0), F (2, –4)
Identify the coordinates of the points A, B, C, D, E, F, G and H shown on the following grid:
A (3, 1) |
B (0, 2) |
C (–2, 2) |
D (–3, 0) |
E (–2, –4) |
F (0, –2) |
G (2, –3) |
H (2, 0) |
Marc has ten square tiles like this: |
He starts his row like this: |
(a) | Write down the coordinates of the next five corners which have a . | ||
---|---|---|---|
(b) | Look at the numbers in the coordinates. Describe two things you notice. | ||
(c) | Marc thinks that (17, 2) are the coordinates of one of the corners which have a . Explain why he is wrong. | ||
(d) |

She places them next to each other in a row, like Marc's tiles. Write down the coordinates of the first two corners which have a . | |||
