# Free Coordinate Geometry 02 Practice Test - 9th Grade

What is the perpendicular distance of the point Q (5,7) from y-axis?

A.

5

B.

7

C.

12

D.

Cannot be determined

#### SOLUTION

Solution : A

The perpendicular distance of a point from y-axis measured along the positive x-axis is abscissa of the point. So, the perpendicular distance of the point Q(5,7) is 5 units from the y-axis.

The perpendicular distance of a point P from the X-axis is 4 units and from the Y-axis is 5 units (in the positive direction). What are the coordinates of point P?

A.

P(5, 4)

B.

P(4, 5)

C.

P(5, 5)

D.

P(4, 4)

#### SOLUTION

Solution : A

The perpendicular distance of the point from the Y-axis measured along the positive X-axis is called the abscissa of the point.

The perpendicular distance of the point from the X-axis measured along the positive Y-axis is ordinate of the point.

The point is P (5,4).

Point (3,-2) lies in ___ Quadrant.

A.

1st

B.

2nd

C.

3rd

D.

4th

#### SOLUTION

Solution : D

Abscissa of the given point is positive and ordinate is negative. So, the point lies in 4th quadrant.

If point 0 represents the origin (0,0), then coordinates of point J shown below is _____ .

​​

A.

(2,4)

B.

(-2,4)

C.

(4,1)

D.

(4,-1)

#### SOLUTION

Solution : B

Point J lies in the second quadrant. So signs of coordinates will be (-,+) .
Distance of J from x axis is 4 hence ordinate is +4. Distance of J from y axis is 2 hence abscissa is -2.
Therefore, coordinates of J are (-2, 4).

An ant moves 3 units along the positive direction of the X-axis from the origin and reaches a point P, then moves 4 units from P along the negative direction of the Y-axis and reaches a point Q. What are the coordinates of points P and Q?

A.

P(3, 0); Q(3, -4)

B.

P(0, 3); Q(3, 4)

C.

P(0, 3); Q(4, -3)

D.

P(-3, 0); Q(-3, 4)

#### SOLUTION

Solution : A

Since the ant is moving 3 units along the positive direction of x-axis from the origin, the coordinate of point P is (3, 0) and then ant moves 4 units along the negative direction of y-axis the coordinates of point Q is (3, -4).

The two axes divide the Cartesian plane into __ quadrants.

#### SOLUTION

Solution :

The reference point in the Cartesian System from which the distances are marked is called the __.

#### SOLUTION

Solution :

The reference point in Cartesian System from which the distances are marked is called the Origin.

The perpendicular distance of a point P from y-axis measured along the positive x-axis is 4 units. Then the ordinate of P is 4.

A.

True

B.

False

#### SOLUTION

Solution : B

Any point on the coordinate plane is represented as (abscissa, ordinate). The abscissa is measured from y-axis along the x-axis direction and the ordinate is measured from x-axis along the y-axis direction. If the perpendicular distance of a point P from y-axis measured along the positive x-axis is 4 units. Therefore, the abscissa of P is 4.

Pavan says that the point P (5, 6) is same as the point Q (6, 5). Is he correct?

A.

True

B.

False

#### SOLUTION

Solution : B

Two points are same only if their abscissae and the ordinates of both the points are equal. Abscissa of point P is 5 and the abscissa of point Q is 6. Since the abscissae of both the points is not the same the points P and Q are not the same.

Which of the points lie in the IV quadrant?

A.

(-2, -4)

B.

(-2, 3)

C. (2, -4)
D. (0.2, -100 )

#### SOLUTION

Solution : C and D

The points with positive abscissa (x-coordinate)  and negative ordinate (y-coordinate) values lie in the IV quadrant. For example (-2, 5).
