Find the coordinates of point P which divides line segment joining A ( 3, -10) and B (3, 2) in such a way that PB: AB= 1.5.
उत्तर
Given: - PB : AB =1 : 5
∴ PB : PA = 1 : 4
Coordinates of Pare
(x , y) = `((4 xx 3 - 3)/5 , (4 xx 2 - 10)/5) = (9/5 , -2/5)`
P`(9/5 , -2/5)`

Activity:
∴ By section formula,
∴ x = `("m"x_2 + "n"x_1)/square`,
∴ x = `(3 xx 8 + 1 xx 4)/(3 + 1)`,
= `(square + 4)/4`,
∴ x = `square`,
∴ y = `square/("m" + "n")`
∴ y = `(3 xx 5 + 1 xx (-3))/(3 + 1)`
= `(square - 3)/4`
∴ y = `square`
