#### Which of the following point lies in the fourth quadrant?

In the fourth quadrant, x-coordinate is positive and y-coordinate is negative. Hence, the point (m, −n) lies in fourth quadrant.

#### The point (3, −5) lies in the ____ quadrant.

The point (3, −5) lies in the fourth quadrant.

#### The abscissa or x-coordinate of any point on Y-axis is:

The abscissa or x-coordinate of anypoint on Y-axis is zero.

#### The point (2, 4) lies in the ____ quadrant.

The x and y coordinates of any point in the first quadrant are positive and positive respectively. Hence, the point (2, 4) lies in the first quadrant.

#### The point (10, 4) lies in the ____ quadrant.

The points of the type (+, +) lie in the first quadrant. Hence, the point (10, 4) lies in the first quadrant.

#### The point A (4, −5) lies in the ____ quadrant.

The x and y coordinates of any point in the fourth quadrant are positive and negative respectively. Hence, the point (4, −5) lies in the fourth quadrant.

#### The point (2, 8) is at 2 units distance from Y-axis.

The abscissa of a point in a cartesian plane represents the distance from Y-axis. Hence, the point (2, 8) is at 2 units distance from Y-axis.

#### The y co-ordinate of the point is called its ………

The y co-ordinate of the point is called its ordinate.

#### If the coordinates of two points are A (-2, 5) and B (4, -6), then (abscissa of A) - (abscissa of B) is

Abscissa of A is -2 and abscissa of B is -6. (Abscissa of A) - (abscissa of B) = -2 - (-6) = -2 + 6 = 4
