Question 11 Mark
The relation between dependent and independent variables is shown through a __________.
Answer
The relation between dependent and independent variables is shown through a graph. Solution: Various types of graph depicts the relation between two variables, one of them is independent and the other is dependent. A graph shows how a change in the independent variable changes the dependent variable.

Question 31 Mark
The points $(3, 5)$ and $(5, 3)$ represent the same point.
Answer
Two ordered pairs are equal, if they have same numbers at corresponding slot, i.e. $x-$coordinates are equal and $Y-$coordinates are equal. Hence, $(3,5)$ and $(5,3)$ are different points.

Question 61 Mark
The y-coordinate of the point $(2, 4)$ is __________.
Answer
The y-coordinate of the point $(2, 4)$ is $4.$
Solution:
In the ordered pair $(2,4),$ i.e. coordinates of a point, the second number is called as the $y-$coordinate of the point. Hence, the $y-$coordinate of $(2,4)$ is $4$

Question 71 Mark
In the point $(4, 7), 4$ denotes the __________.
Answer
In the point $(4, 7), 4$ denotes the x-coordinate (abscissa).Solution:
First number (coordinate) of the ordered pair is called as the $x-$coordinate or abscissa. Hence, in the point $(4,7),4$ denotes the $x-$coordinate.

Question 81 Mark
In the point $(2, 3), 3$ denotes the $y-$coordinate.
Answer
In the ordered pair $(2,3),$ the second number is called the $y-$coordinate or ordinate of the number.
Hence, $3$ denotes the y-coordinate of the point.

Question 91 Mark
For fixing a point on the graph sheet we need two coordinates.
Answer
 To plot a point on the graph sheet we require two numbers, known as coordinates viz. the $x-$coordinate and the y-coordinate.

Question 101 Mark
The distance of the point $(3, 5)$ from the $y-$axis is $5.$
Answer
 We know that the $x-$coordinate of a point represents the distance of the point from $Y-$axis. Here $x-$coordinate is $3,$ so the distance of the point $(3,5)$ from the $Y-$axis is $3.$

Question 111 Mark
The ordinate of a point is its distance from the $y-$axis.
Answer
The ordinate of a point is nothing but coordinate of the point and the $y-$coordinate denotes the distance of a point from $X-$axis.

Question 121 Mark
The $y-$coordinate of any point lying on the $x -$axis will be zero.
Answer
The distance of the points which lie on $X-$axis, will be zero from the $X-$axis, i.e. $y-$coordinate is zero for the points lying on $X-$axis.

Question 131 Mark
We need ________ coordinates for representing a point on the graph sheet.
Answer
We need pair of (or two) coordinates for representing a point on the graph sheet.
Solution:
To represent the position of a point on the graph sheet we require two measures namely $x-$coordinate and $y-$coordinate.

Question 141 Mark
A point in which the $x-$coordinate is zero and $y-$coordinate is non-zero will lie on the _________.
Answer
A point in which the $x-$coordinate is zero and $y-$coordinate is non-zero will lie on the Y-axis.
Solution: Since, the $x-$coordinate is zero, i.e. the distance of the point from $Y-$axis is $0$, the point lies on the $Y-$axis at a certain distance from the origin, which is given by $y-$coordinate.

Question 151 Mark
The horizontal and vertical line in a line graph are usually called __________ and __________.
Answer
The horizontal and vertical line in a line graph are usually called X-axis and Y-axis Solution: To draw a graph we need pairs of points known as coordinates and to plot a point we require two mutually perpendicular axes, also known as the $X-$axis $($horizontal line$)$ and the $Y-$axis $($vertical line$).$

Question 161 Mark
The point where the two axes intersect is called the __________.
Answer
The point where the two axes intersect is called the origin. Solution: The $X-$axis and $y-$axis intersect each other at the point representing the origin. Coordinates of origin are $(0, 0).$

Question 171 Mark
For the point $(5, 2)$, the distance from the $x -$axis is __________ units.
Answer
For the point $(5, 2),$ the distance from the $x -$axis is $2$ units.
Solution:
We know that, the $y-$coordinate represents the distance of the point from the $X-$axis. ;Hence, the point $(5,2)$ is at a distance of $2$ units from the $X-$axis.

Question 181 Mark
The process of fixing a point with the help of the coordinates is known as __________ of the point.
Answer
The process of fixing a point with the help of the coordinates is known as plotting of the point.
Solution:
To locate the exact position of a point we need two coordinates viz, the $x-$coordinate and the $y-$coordinate and this process of finding the position or representing the numbers on a graph sheet with the help of the coordinates is known as plotting of the point.

Question 191 Mark
A point has $5$ as its $x-$coordinate and $4$ as its $y-$coordinate. Then, the
coordinates of the point are given by________.
Answer
A point has $5$ as its $x-$coordinate and $4$ as its $y-$coordinate. Then, the
coordinates of the point are given by $(5, 4).$
Solution: To denote a point in $2-D,$ we use two numbers viz. the $x-$coordinate, the $y-$coordinate. In the ordered pair, the $x-$coordinate is written in the first slot and the $y-$coordinate in the second slot separated by comma. Hence, the required point is $(5, 4).$

Question 231 Mark
The $x-$coordinate of any point lying on the $y-$axis will be __________.
Answer
The $x-$coordinate of any point lying on the $y-$axis will be zero.
Solution:
Since, the $x-$coordinate represents the distance of the point from $Y-$axis is zero, therefore the points lying on the $Y-$axis have $x-$coordinate as zero.

Question 241 Mark
All points with $y-$coordinate as zero lie on the __________.
Answer
All points with $y-$coordinate as zero lie on the X-axis.
Solution:
Since, $y-$coordinate is zero, i.e. the distance of the point from $X-$axis is zero.
Hence, the points lies on the $X-$axis.
