    Let two points beA (x₁,y₁,) and B(x₂,y₂).

    If  P (x,y) is a point on the line segment AB which divides AB in the ratio m:n internally, then

    x = (mx₂ + nx₁)(m + n)  y = (my₂ + ny₁)/(m + n)

    Here,

    let coordinates of P be (x,y)

    Given P divides in ratio 3:7

    x = [3(-2) + 7(-2)]/(3+7)       y = [3(-4) + 7(-2)]/(3+7)

    x = -2 and y = -13/5

    P = (-2,-13/5)
