This is an easy 1-mark question from the chapter Coordinate Geometry. Concept tested: Distance between two points. One of the points is the origin whose coordinates are (0, 0).

Question 3: Find the distance of a point P(x, y) from the origin.

online.maxtute.com

Distance between two points A(x_{1}, y_{1}) and B(x_{2}, y_{2}) = \\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2})

Let origin be Point A. So, (x_{1}, y_{1}) = (0, 0)

Let P(x, y) be point B. So, (x_{2}, y_{2}) = (x, y)

∴ distance between (x, y) and (0, 0) = \\sqrt{(x - 0)^2 + (y - 0)^2})

= \\sqrt{x^2 + y^2})
