The point can be found as the weighted average of the given points, with the weights being the reverse of the line segment ratio values. The dividing point D will be

... D = (3*(4, 8) + 1*(14, 10))/(3 + 1) = (12+14, 24+10)/4

... D = (6 1/2, 8 1/2) . . . . . matches your second selection

Answer:

D = (3*(4, 8) + 1*(14, 10))/(3 + 1) = (12+14, 24+10)/4

D = (6 1/2, 8 1/2) . . . . . matches your second selection
