Class 9 Maths — Coordinate geometry

Read and plot points on the coordinate plane and name the quadrant they lie in.

Before you start

The two axes cut the page into four quarters. Find out what each one is called — all four, in any order, nothing to get right.

They are numbered anticlockwise from the top right. Both coordinates are positive in the first and both are negative in the third.

1.In which quadrant does the point (3, 5) lie?
- a) Second
- b) Fourth
- c) First
- d) Third
2.Sort each point by which axis it sits on.
Groups: On the x-axis · On the y-axis
- (0, -7)
- (0, 5)
- (0, 2)
- (5, 0)
- (-3, 0)
- (9, 0)
3.In which quadrant does the point (5, -1) lie?
- a) First
- b) Second
- c) Fourth
- d) Third
4.Match each point to where it lies.
- (2, 3)
- (-2, 3)
- (-2, -3)
- (2, -3)
- (0, 0)
- Second quadrant
- The origin
- Fourth quadrant
- First quadrant
- Third quadrant
5.A rectangle has corners at (0, 0), (6, 0), (6, 4) and (0, 4). What is its area, in square units?
6.In which quadrant does the point (-4, 2) lie?
- a) Third
- b) Fourth
- c) Second
- d) First
7.How far is the point (6, 8) from the y-axis? Give just the number.
8.What is the x-coordinate of the point (7, -3)?

1. c) First
2. (5, 0) → On the x-axis; (0, 5) → On the y-axis; (-3, 0) → On the x-axis; (0, -7) → On the y-axis; (9, 0) → On the x-axis; (0, 2) → On the y-axis
3. c) Fourth
4. (2, 3) → First quadrant; (-2, 3) → Second quadrant; (-2, -3) → Third quadrant; (2, -3) → Fourth quadrant; (0, 0) → The origin
5. 24
6. c) Second
7. 6
8. 7
