    Step-by-step explanation:

    Suppose the point P(−3,p) divides the line segment joining points A(−5,−4)≡(x2,y2) and B(−2,3)≡(x1,y1) in the ratio k:1.

    Section formula: [x=(m+nmx1+nx2)] and [y=(m+nmy1+ny2)]

     Then, the coordinates of P are(k+1−2k−5k+13k−4)

    But, the coordinates of P are given as (−3,p).

    ∴k+1−2k−5=−3andk+13k−4=p

    ⇒−2k−5=−3k−3andk+13k−4=p

    ⇒k=2andp=k+13k−4
