Class 10 - Mathematics - CHAPTER 7: Coordinate Geometry - Exercise 7.1

Question 1

Step 1: A point in a plane is written as \((x,y)\).

Here, the given point is \(P(2,3)\), so \(x = 2\) and \(y = 3\).

Step 2: The x-axis is the horizontal axis. The distance of a point from the x-axis depends only on its y-coordinate.

Step 3: Formula: Distance from x-axis = \(|y|\).

Step 4: For \(P(2,3)\), \(y = 3\). So distance = \(|3| = 3\).

Step 5: Therefore, the distance of the point from the x-axis is 3 units. If we measure in SI, we say it is 3 metres (m).
