Overview
This page provides Class 9 Maths Exercise 1.1 practice for The Use of Coordinates, including position description, ordered pairs, and coordinate-grid reasoning.
Coordinate Basics and Position Mapping
Q1: Position on a Table
Describe the position of an object kept on a rectangular table using two perpendicular edges as reference lines.
Choose one edge as the horizontal reference and the adjacent edge as the vertical reference.
Measure the object's distance from both edges.
The position can be written as an ordered pair of distances, such as $(x, y)$.
Q2: Ordered Pair
If a point is 4 units to the right of the vertical axis and 3 units above the horizontal axis, write its ordered pair.
The horizontal distance gives the first coordinate.
The vertical distance gives the second coordinate.
The ordered pair is $(4, 3)$.
Q3: Locate a Point
What does the ordered pair $(0, 5)$ tell you about the point's position?
The first coordinate is 0, so the point lies on the vertical axis.
The second coordinate is 5, so the point is 5 units above the origin.
The point lies on the positive vertical axis, 5 units above the origin.
