Question

The points whose abscissa and ordinate have different signs will lie in:

• A. $I$ and $II$ quadrants
• B. $II$ and $III$ quadrants
• C. $I$ and $III$ quadrants
• D. $II$ and $IV$ quadrants

Answer 1

The correct option is D $II$ and $IV$ quadrants

A coordinate is an ordered pair of numbers in which the first number is the abscissa i.e. the measurement along the $X$ axis and the second number is the ordinate i.e, the measurement along the $Y$ axis.

The signs of the coordinates in the first quadrant is $(+,+)$,

the second quadrant is $(-,+)$,

the third quadrant is $(-,-)$,

fourth quadrant is $(+,-)$.

So, the points whose abscissa and ordinate have different signs are $2^{nd}$ and $4^{th}$ quadrants.
