A coordinate grid has a horizontal x-axis and a vertical y-axis that meet at the origin, (0, 0). A point is named by two numbers in brackets, like (4, 3).
The first number tells you how far to go across, along the x-axis. The second tells you how far to go up, along the y-axis. So (4, 3) is 4 across and 3 up. The order matters: (3, 4) is a different point.
Worked example
Point A is 6 squares across and 2 squares up from the origin. What are its coordinates?
- Across comes first: 6.
- Up comes second: 2.
Answer:(6, 2)
Key words
- x-axis
