Question

If the coordinates of $(x,y)$ lie in first quadrant then

• A. $x=1,y=7$
• B. $x=6,y=-2$
• C. $x=-3,y=7$
• D. None of these

Answer 1

The correct option is A $x=1,y=7$

In first quadrant $x$ and $y$ are positive. Hence $x$ takes the value $1$ and $y$ takes the value $7$

$\therefore x=1,y=7$
