Answer:
The value of m is 0.
Step-by-step explanation:
Let the point P divides the line AB in k:1.
The coordinates of line AB are A (2, 3) and B (6, -3).
The coordinates of P are (4,m).
By section formula, if a point divides a line in m:n, then
It means the point P divides the line AB in 1:1. So, P is the midpoint of AB.
Therefore the value of m is 0.
