**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).**

**Solution:**

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).**
