6.2 Division of a Line Segment
(A) Midpoints of a Line Segment
Formula for the midpoint, M of A (xl, y1) and B (x2, y2) is
Given B (m – 4, 3) is the midpoint of the straight line joining A(–1, n) and C (5, 8). Find the values of m and n.
(B) Point that Internally Divides a Line Segment in the
Ratio m : n
Formula for the point P that lies on AB such that AP : PB = m : n is
The coordinate of R(2, –1) divide internally the line of AB with the ratio 3 : 2. If coordinate of A is (–1, 2), find the coordinate of B.
