Step-by-step explanation:
If a point divides the line segment AB joining two points in given ratio m:n internally, by section formula, the co-ordinates of a point are given as =(
m+n
mx
2
+nx
1
,
m+n
my
2
+ny
1
)
The ratio is m:n=2:1 and A(x
1
,y
1
) = (3,4) and B(x
2
,y
2
) = (7,−6)
∴ Point =(
m+n
mx
2
+nx
1
,
m+n
my
2
+ny
1
)
=(
2+1
2×7+1×3
,
2+1
2×(−6)+1×4
)
=(
3
17
,
3
−8
)
∴ The point lies in IV quadrant.
