(D) If $P(x, y)$ divides the line segment joining $A(x_1, y_1)$ and $B(x_2, y_2)$ internally in the ratio $m: n$,then the coordinates are given by the section formula:$x = \frac{mx_2 + nx_1}{m + n}$ and $y = \frac{my_2 + ny_1}{m + n}$Given that $x_1 = 7, y_1 = -6, x_2 = 3, y_2 = 4, m = 1$ and $n = 2$.Substituting these values into the section formula:$x = \frac{1(3) + 2(7)}{1 + 2} = \frac{3 + 14}{3} = \frac{17}{3}$$y = \frac{1(4) + 2(-6)}{1 + 2} = \frac{4 - 12}{3} = -\frac{8}{3}$Thus,the point is $(\frac{17}{3}, -\frac{8}{3})$.Since the $x$-coordinate is positive and the $y$-coordinate is negative,the point lies in the $IV$ quadrant.
