Question

Points P, Q, R and S divide a line segment joining A(2,6) and B(7,-4) in five equal parts. Find the coordinates of Point and R​

Answer 1

Step-by-step explanation:

ANSWER

P, Q, R, S divide the line segment AB on the ratio 1:4,2:3,3:2,4:1 respectively.

From above P divides AB in 1:4 ratio

coordinates of P using section formula,

m+n

=7

⇒

7+8

⇒(2,3)= coordinates of P

Similarly,

Coordinates of Q,

Q divide AB in 2:3 ratio,

⇒

12+3

,

5

14+6

⇒ (3,4)= coordinates of Q

Similarly,

R divide AB in 3:2 ratio,

Coordinates of R,

⇒

21+4

⇒ (4,5)= coordinates of R
