find the ratio in which the line 2x + 3y - 5 = 0 divideds the line segment joining the points (8,-9) and (2,1) . also find the coordinates of the point of division.

Let the co-ordinates be P (*x*, *y*). Let the ratio be *m *: *n* in which the line 2*x* + 3*y* – 5 = 0 divides the line segment joining the points (8, –9) and (2, 1)

Since this point P lies on the line joining the points (8, –9) and (2, 1) and divide the line segment in the ratio *m *: *n*.

So, the co-ordinates of point P are

Since this point P also lies on the given line 2*x* + 3*y* – 5 = 0, so it must satisfy the equation of this line. so,

Hence *m *: *n* = 8: 1

and so the co-ordinates of point of division are
