The co-ordinates of the mid-point of line joining the points A and B are (2, -3). If the co-ordinates of point A are (-3, 4), then find the co- ordinates of point B.

Explanation

To find the coordinates of point B given the midpoint and the coordinates of point A, we can follow these steps:

### Step 1: Understand the Midpoint Formula
The midpoint \( M(x_m, y_m) \) of a line segment joining two points \( A(x_1, y_1) \) and \( B(x_2, y_2) \) is given by the formula:
\[ M = \left( \frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2} \right) \]
In this case, we know the midpoint \( M \) is (2, -3) and the coordinates of point A are (-3, 4).
