Question

The diagram shows a rectangle on a cartesian plane. $M$ is the mid-point of $PQ$. The coordinates of $R$ are:

• A. $(9,6)$
• B. $(8,6)$
• C. $(9,1)$
• D. $(10,6)$

Answer 1

The correct option is A $(9,6)$

y-component of R is 6

x-component of R $=x$ component of Q

$i.e.,\frac{x+1}{2}=5$

$x=9$

$\therefore R=(9,6)$
