A point both of whose coordinates are negative will lie in
a. I quadrant
b. II quadrant
c. III quadrant
d. IV quadrant

Solution:

(x, y) are called the coordinates of the point whose abscissa is x and the ordinate is y.

Signs of the coordinates of a point in the first quadrant are (+, +), in the second quadrant (–, +), in the third quadrant (–, –) and in the fourth quadrant (+, –)

Therefore, the point both of whose coordinates are negative will lie in III quadrant.

✦ Try This: Point (0, 9) lies a. on the x-axis, b. in the second quadrant, c. on the y-axis, d. in the fourth quadrant
