Coordinate Geometry (1 Mark Questions and Answers)

Class 10 - Maths - Very Short Answers Based Questions

Q1: What will the formula calculate the distance between two points that lie on the x-axis?

Answer: Let P(x₁, 0) and Q(x₂, 0) are two points on x-axis. PQ = |x₂ - x₁|.


Q2:  Where do these following points lie (0, -3), (0, -7), (0, 6), (0, 9)?

Answer: Since The x-coordinates of each point is zero. ∴ Given points are on the y-axis.
