Answer 2

Answer:

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

line joining the points (x1,y1) and (x2,y2) in the ratio m:n, then (x,y)=(m−nmx2−nx1,m−nmy2−ny1)

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

R=(4+34(2)+3(1),4+34(3)+3(2))=(711,718)Using the section formula, if a point (x,y) divides the
