The line segment joining the points M (5, 7) and N (-3, 2) is intersected by the y-axis at point L. Write down the abscissa of L. Hence, find the ratio in which L divides MN. Also, find the co-ordinates of L.
Since, point L lies on y-axis, its abscissa is 0. Let the co-ordinates of point L be (0, y). Let L divides MN in the ratio k: 1 using section formula,we have
