If the x-coordinate of a point is zero, then this point lies:
-
I quadrant
-
II quadrant
-
X-axis
-
Y-axis
Correct Answer
A. Y-axisExplanation
If the x-coordinate of a point is zero, it means that the point lies on the y-axis. This is because the y-axis is the vertical line where the x-coordinate is always zero. Therefore, any point with a zero x-coordinate will lie on the y-axis.Rate this question:

If the perpendicular distance of a point P from the x-axis is 7 units and the foot of the perpendicular lies on the negative direction of the x-axis, then the point P has:
-
Y-coordinate = 7 or –7 only
-
Y-coordinate = 7 only
-
Y-coordinate = –7 only
-
X-coordinate = –7
Correct Answer
A. Y-coordinate = 7 or –7 onlyExplanation
The y-coordinate of a point represents its distance from the x-axis. Since the foot of the perpendicular lies on the negative direction of the x-axis, the point P can have a y-coordinate of either 7 or -7.Rate this question:

If P (–3, 8), Q (7, –5), R (–3, –8) and T (–7, 9) are four points in the Cartesian plane. Then the point(s) in the third quadrant is/are:
-
P and T
-
Q and R
-
R only
-
P and R
Correct Answer
A. R onlyExplanation
The point R (-3, -8) is the only point in the third quadrant. The third quadrant is defined as the area where both the x-coordinate and y-coordinate are negative. In this case, both the x-coordinate (-3) and y-coordinate (-8) of point R are negative, placing it in the third quadrant. Therefore, the correct answer is R only.Rate this question:

The coordinates of any point on the y-axis are of the form (0, k), where |k| is the distance of the point from the:
-
Y-axis
-
X-axis
-
Origin
-
None of these
Correct Answer
A. X-axisExplanation
The coordinates of any point on the y-axis are of the form (0, k), where |k| is the distance of the point from the x-axis. This is because the y-axis is a vertical line that passes through the origin, and the x-coordinate of any point on the y-axis is always 0. Therefore, the distance of any point on the y-axis from the x-axis is measured along the x-axis, which is the x-axis itself.Rate this question:

Which point lies to the right of Y-axis?
-
(-2,-1)
-
(2,1)
Correct Answer
A. (2,1)Explanation
The point (2,1) lies to the right of the Y-axis because the X-coordinate is positive. In a Cartesian coordinate system, the Y-axis is the vertical line that divides the plane into two halves. The positive X-axis is to the right of the Y-axis, and the negative X-axis is to the left. Since the X-coordinate of (2,1) is positive, it is to the right of the Y-axis.Rate this question:

Fox x=3, y= 2, u= 9, v= -13 the point ( x+y, u+v) lies in the ----- quadrant
-
I quadrant
-
II quadrant
-
IIIquadrant
-
IV quadrant
Correct Answer
A. IV quadrantExplanation
The point (x+y, u+v) can be calculated as (3+2, 9+(-13)) which equals (5, -4). In the coordinate plane, the positive x-axis is to the right and the positive y-axis is upwards. Since the x-coordinate is positive and the y-coordinate is negative, the point lies in the IV quadrant.Rate this question:

The point at which the two coordinate axes meet is called the
-
Abscissa
-
Ordinate
-
Origin
-
Quadrant
Correct Answer
A. OriginExplanation
The point at which the two coordinate axes meet is called the origin. This is the starting point or reference point for measuring distances on a coordinate plane. It is represented by the coordinates (0,0) and is where the x-axis and y-axis intersect.Rate this question:

In the given figure, coordinates of P are
-
(-4,-2)
-
(-2,-4)
-
(-2,4)
-
(4,-2)
Correct Answer
A. (-2,4)Explanation
The correct answer is (-2,4) because it is the only option that matches the given coordinates. The coordinates of P are (-2,4) as indicated in the figure.Rate this question:

On joining the points (0,0), (0,2), (2,2) and (2,0) we obtain a
-
Square
-
Rectangle
-
Rhombus
-
Parallelogram
Correct Answer
A. SquareExplanation
The given points form a square because all sides are equal in length and all angles are right angles. A square is a type of quadrilateral where all sides are equal and all angles are right angles.Rate this question:
