Video Explanation

Explanatory Answer | Chapter 3 Extra Question 1

The table given below provides details about the signs of the abscissa (x-coordinate) and ordinate (y-coordinate) in the four quadrants in the x-y plane.

(i) (6, 3)
Abscissa (x – cordinate) and ordinate (y – coordinate) are both positive.
Therefore (6, 3) lies in the first quadrant.

(ii) (-8, 4)
Abscissa (x – cordinate) is negative and ordinate (y – coordinate) is positive.
Therefore (-8, 4) lies in the second quadrant.

(iii) (8, -7)
Abscissa (x – cordinate) is positive and ordinate (y – coordinate) is negative.
Therefore (8, -7) lies in the fourth quadrant.

(iv) (-5, -9)
Abscissa (x – cordinate) and ordinate (y – coordinate) are both negative.
Therefore (-5, -9) lies in the third quadrant.
