If R(5,6) is the midpoint of the line segment A B joining the points A(6,5) and B(4,4) then y equals (a) 5 (b) 7 (c) 12 (d) 6

The correct option is option b) 7

Since \mathrm{R}(5,6) is the midpoint of the line segment AB joining the points

\mathrm{A}(6,5) and \mathrm{B}(4, \mathrm{y}), therefore

\frac{5+y}{2}=6

\Rightarrow 5+y=12

\Rightarrow y=12-5=7
