Answer Key – Class 9 Maths Chapter 1 MCQs
- B — (0, 0): The origin is the point where the x-axis and y-axis intersect.
- A — X-axis: The x-axis is horizontal.
- C — Y-axis: The y-axis is vertical.
- C — 5: The first value in an ordered pair is the x-coordinate.
- B — 7: The second value is the y-coordinate.
- C — (4, 0): A point on the positive x-axis has a positive x-coordinate and y-coordinate zero.
- B — (0, 5): A point on the positive y-axis has x-coordinate zero and a positive y-coordinate.
- A — First quadrant: Both coordinates are positive.
- B — Second quadrant: The x-coordinate is negative and the y-coordinate is positive.
- C — Third quadrant: Both coordinates are negative.
- D — Fourth quadrant: The x-coordinate is positive and the y-coordinate is negative.
- C — 0: Every point on the x-axis has y-coordinate zero.
- A — 0: Every point on the y-axis has x-coordinate zero.
- C — (-4, -5): Both coordinates are negative in the third quadrant.
- B — (4, 3): Right means positive x, and above means positive y.
