Hence 3 is the correct answer.
Therefore option (A) is correct
Question:1
Answer: FalseSolution.
False, because point (3, 0) lies on x axis.
It does not lie in the first quadrant.
Points which lie in the first quadrant have both x and y coordinates as positive.
Examples: (1, 3) (2, 4) etc.
Therefore the given statement is False.

Answer: FalseSolution.
False, point (1, -1) and (-1. 1) lie in the different quadrants.
Point (1, -1) lies in the IV quadrant and point (-1. 1) lies in the II quadrant.
Therefore the given statement is False.
Question:3
Answer: FalseThe abscissa is the x-axis (horizontal) coordinate
The ordinate is the y-axis (vertical) coordinate
Here ordinate is -1/2 and abscissa is 1.
So the coordinates are (1, -1/2) and not (-1/2, 1) .
Therefore the given statement is False.
Question:4
Answer: FalseSolution.
We know that points that lie on the y-axis have coordinate in the form (0, y).
So we can say that x-coordinate should be zero.
The distance from x-axis will be equal to its y-coordinate.
So the point will be (0, 2)
But here the point is given as (2, 0) so the statement is false.
Question:5
Answer: TrueSolution.
We know that signs in II quadrant are (-, +) and here we have the point as (-1, 7)
i.e., x-coordinate is negative and y-coordinate is positive.
Therefore the given statement is True.

Plot the following points and check whether they are collinear or not :
(0, 0), (2, 2), (5, 5)
Plotting the given points:
(0, 0), (2, 2), (5, 5)

Solution.
We know that sign in I quadrant = (+, +)
In II quadrant = (-, +)
In III quadrant = (-,-)
In IV quadrant = (+,-)
Abscissa is the x-axis (horizontal) coordinate
Ordinate is the y-axis (vertical) coordinate
(i) Hence abscissa is -3 and ordinate is 5.
So, it lies in II quadrant.
(ii) Here x coordinate is -5 and y-coordinate is -3
So both are negative.
Its lies in III quadrant.
(iii) Abscissa is -5 and ordinate is 3
Here x coordinate is -5 and y-coordinate is 3
So it lies in II quadrant.
(iv) Ordinate is 5 and abscissa is 3
Here x coordinate is 3 and y-coordinate is 5
Both are positive.
So it lies in I quadrant

R = (3, 0)
Q = (3, -1)
(ii) 0
Solution.
We have,
All the points lie on a line where x coordinate is fixed, i.e., 3.
(i) Coordinate of the points P
Distance from x-axis: 2 units
So coordinates are (3, 2)
Coordinate of the points R
Distance from x-axis: 0 unit
So coordinates are (3, 0)
Coordinate of the points Q
Distance from x-axis:
So coordinates are (3, -1)
(ii) Abscissa is the x-axis (horizontal) coordinate
All the points lie on a line where x coordinate is fixed, i.e., 3.
So abscissa of L and M is the same, i.e., 3
Hence difference = 3 - 3 = 0

(-1.75, -0.25) = (-7 units, -1 unit)
The graph will be as follows:
Question:10
Answer: (7,0)Solution.
We know that the point that lies on x-axis must have its y-coordinate as zero.
Here it is given that a point lies on the x-axis at a distance of 7 units from the y-axis.
So y-coordinate = 0
x-coordinate is the perpendicular distance from the y-axis which is given as 7 units
So, x-coordinate is 7.
Hence coordinates are (7, 0)

Solution.
(i) We know that the point which lies on x-axis and y-axis both is origin whose coordinates are (0, 0)
(ii) We know that the point that lies on y-axis must have its x-coordinate as zero.
Here it is given that a point lies on the y-axis with ordinate -4
The ordinate is the y-axis (vertical) coordinate
So y-coordinate = -4
Hence coordinates are (0, -4)
(iii) We know that the point that lies on x-axis must have its y-coordinate as zero.
Here it is given that the point lies on the x-axis with abscissa 5
The abscissa is the x-axis (horizontal) coordinate

Answer:
Answer:Coordinates of A (-5, 0)
Coordinates of B (-5, -3)
Coordinates of C (0, -3)
Coordinates of O (0, 0)
Solution.
Given rectangle has one vertex at the origin. Let the vertex be O.
∴ The coordinates of O are O (0, 0).
Let the rectangle be OABC.
Length = 5 units
Breadth = 3 units.
Now as the longer side is on the x-axis, we get that length lies on x-axis and breadth lies on the y axis.
So,
The coordinates of A are A (-5, 0)
The coordinates of C will be (0, -3).
Given that one of the vertex is in the third quadrant.
So, the rectangle lies in the III quadrant.
The coordinates of B will be (-5, -3).

Length of PQ = 4 -1 = 3 units
Let coordinates of point R be (x, y)
Now, as PQRS is a square (PQ = QR = RS = SP)
Consider,
PQ = RS
3 = x - 1
So, x = 4
Similarly,
PQ = QR
3 = y - 0
So, y = 3
Hence, R is (4, 3)
The graph is as follows:

(ii) G (5, 0); I (-2, 0)
(iii) D (-5, 1); H (-5, -3)
Abscissa is the x-axis (horizontal) coordinate
Ordinate is the y-axis (vertical) coordinate
(i) Abscissa is given as 0
So, x-coordinate must be zero.
Hence points are A (0, 3); L (0, -4)

So, y-coordinate must be zero.
Hence points are G (5, 0); I (-2, 0)
(iii) Abscissa is given as -5
So, x-coordinate must be -5.
Hence points are D (-5, 1); H (-5, -3)
