Answer» Using the SECTION FORMULA, if a POINT (x,y) divides the LINE joining thepoints (x 1 ,y 1 ) and (x 2 ,y 2 ) internallyin the ratio m:N, then (x,y)=( m+nmx 2 +nx 1 , m+nmy 2 +ny 1 )Substituting (x 1 ,y 1 )=(4,−3) and (x 2 ,y 2 )=(−1,7) and m=3,n=2 in the section formula, we getthe abscissa of the point ( 3+23(−1)+2(4) )=1 |
