Question

If $MN$ is a straight line on a cartesian plane. The co-ordinates of N are $(12,13)$ and $MN=9$ units. Find the co-ordinates of M.

• A. $(21,13)$
• B. $(12,22)$
• C. $(12,4)$
• D. $(3,13)$

Answer 1

The correct option is D $(3,13)$

Coordinate of N=$(12,13)$

Distance of MN=$9$ units

As it is given in x-direction =$(12-9)$units =$3$ units

$\therefore$ Coordinate of M=$(3,13)$
