Question

Prove that originO divides the line joining the point A(1,-3)andB(-3,9) in the ratio 1:3 internally find the coordinates of the point which externally divides the line

Answer 1

Answer:

Let the point be P(x,y)

x=(m2x1+m1x2)÷(m1+m2).

=>(3×1+1×-3)÷(1+3)

=>(3-3)÷4

=>0/4

=>0

y=(y2m1+y1m2)÷(m1+m2)

=>(9×1+3×-3)÷(1+3)

=>(9-9)÷4

=>0\4

=>0

so, P(0,0)

It's origin.
