# Abscissa of a point is positive in

a. I and II quadrants

b. I and IV quadrants

c. I quadrant only

d. II quadrant only

**Solution:**

In the coordinate (x, y) is used to denote the point in the cartesian plane

The first coordinate x is called the abscissa while the second coordinate is called the ordinate

Abscissa is the distance of point from y axis scaled with x axis

Ordinate is the distance of point from x axis scaled with y axis

Both abscissa and ordinate are together known as coordinates

We know that the signs of the coordinates are

+, + in the I quadrant

-, + in the II quadrant

-, - in the III quadrant

+, - in the IV quadrant

The abscissa is positive in the I and IV quadrant

Therefore, the abscissa of a point is positive in I and IV quadrants.
