Using the section formula, if a point (x,y) divides the line joining the

points (x1​,y1​) and (x2​,y2​) internally in the

ratio m:n, then (x,y)=(mx2​+nx1)/m+n ​​,(my2​+ny1​​)/m+n

Substituting (x1​,y1​)=(7,−6) and (x2​,y2​)=(3,4)  and m=1,n=2 in the section formula, we get

After solving we get x = 17/3 and y = -8/3

Since, x− cordinate is positive and y− cordinate is negative, the point lies in the IV quadrant.
