The coordinate of a point P on the line segment joining A(1,2) and B(6,7) such that AP=2AB5, is
Here, point P is on AB such that AP=2AB5⇒APAB=25.
Using componendo and dividendo, we have,
AP(AB−AP)=2(5−2)
APPB=23
This means that P divides AB in the ratio 2:3.
Therefore, coordinates of P will be,
⇒P(2×6+3×12+3,2×7+3×22+3)
⇒P(3,4)
Hence, the required point is P(3,4).
Points P, Q, R and S divide the line segment joining the points A (1, 2) and B(6, 7) into five equal parts. Find the coordinates of the points P, Q and R.
