Signs of the abscissa and ordinate of a point in the second quadrant are respectively
(A) +, +
(B) –, –
(C) –, +
(D) +, –
Answer: [C] –, +
Solution.
We know that the x-coordinate is called the abscissa and the y-coordinate is also called the ordinate.
Thus in the second quadrant abscissa is negative and ordinate is positive.
So, in the second quadrant, signs of the abscissa and ordinate are (–, +)
Therefore option (C) is correct.
