Question

State the quadrant in which the coordinate $(15,-2)$ lies:

• A. $I$
• B. $IV$
• C. $II$
• D. $III$
• E. none of these

Answer 1

Answer: (B)

Given point is $(15,-2)$.

We know,

In $I^{st}$ quadrant, both $x$ and $y$ are positive,
In $I{I}^{nd}$ quadrant, $x$ is negative and $y$ is positive,
In $II{I}^{rd}$ quadrant, both $x$ and $y$ are negative
and in $I{V}^{th}$ quadrant, $x$ is positive and $y$ is negative.

In $(15,-2)$, $x$ is positive and $y$ is negative.
Therefore, $(15,-2)$ lies in $I{V}^{th}$ quadrant.
Option $B$ is correct.
