# 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

**Solution:**

In the cartesian plane, the coordinates (x, y) denotes the point

Here x is the abscissa and y is the ordinate

Distance of point from y axis scaled with x axis is known as the abscissa

Distance of point from x axis scaled with y axis is known as the ordinate

The abscissa and ordinate together are called the coordinates

The signs of the coordinates in the quadrants are

I quadrant - +, +

II quadrant - -, +

III quadrant - -, -

IV quadrant - +, -

Therefore, the points whose abscissa and ordinate have different signs will lie in II and IV quadrants.
