Find the ratio in which the point P (x, 2) divides the line segment joining the points A (12,5) and B (4, -3). Also, find the value of x.

Here, given points are A (12,5) and B (4, -3) and let the point dividing the line joining two points be P(x,2)


Let the ratio be m:n



By section formula,


x = , y =


For point P(x,2),


x = …(1)


And 2 = …(2)


Solving 2 for finding ratio between m and n,


2 =


2(m + n) = -3m +5n


2m + 2n = -3m +5n


5m = 3n


=


m : n = 3 : 5


Now solving for equation 1, where m = 3 and n =5


x =


x =


x = 9


Hence, our point is (9, 2)
