Solution

Let the coordinates of point P be (x, y). 
The ratio in which P divides A(–1,7) and B(4,–3) is 2 : 3.
Using the section formula we have 

\[x = \frac{4 \times 2 + 3 \times \left( - 1 \right)}{2 + 3} = \frac{8 - 3}{5} = 1\]

\[y = \frac{2 \times \left( - 3 \right) + 3 \times 7}{2 + 3} = \frac{- 6 + 21}{5} = 3\]

Thus, the coordinates of point P are (1, 3).
