Worked examples
Two examples
Example 1
A point is 2 to the left of the y-axis and 5 above the x-axis. What are its coordinates?
- Across first: 2 to the left, so x = −2.
- Then up: 5, so y = 5.
Answer: (−2, 5)
Example 2
A point sits on the x-axis, 4 to the right of the origin. What are its coordinates?
- x = 4. On the x-axis, y = 0.
Answer: (4, 0)
