Section Formula CBSE NCERT Solutions Chapter 7 Exercise 7.2 Question 7
7. Find the coordinates of a point A, where AB is the diameter of a circle whose centre is (2, -3) and B is (1, 4).
We want to find coordinates of point A. AB is the diameter and coordinates of center
are (2, -3).
And, coordinates of point B are (1, 4).
Let coordinates of point A are (x, y)
Using section formula, we can say that
Using section formula, we can also say that
Therefore, Coordinates of point A are (3, -10).
