The y-coordinate of the point (2, 4) is __________.
Solution: 4 units.
Explanation:
In the ordered pair, the first number always represents the x coordinate, and the second number represents the y coordinate. Hence, the y coordinate is 4 units.
In the point (4, 7), 4 denotes the __________.
Solution: x- coordinate.
Explanation:
The first number in the ordered pair represents the x-coordinate, and the second number represents the y- coordinate.
A point has 5 as its x – coordinate and 4 as its y–coordinate. Then the coordinates of the point are given by __________.
Solution: (5, 4)
Explanation:
The point is represented using the ordered pair = (x coordinate, y coordinate)
In the coordinates of a point, the second number denotes the
__________.
Solution: y coordinate
Explanation:
The second number in the coordinate point represents the y coordinate.
The point where the two axes intersect is called the __________.
Solution: Origin (0, 0)
Explanation:
The two axis intersects at a common point in the graph is called the origin.
In questions 26 to 34, state whether the statements are true (T) or false (F).
For fixing a point on the graph sheet, we need two coordinates.
Solution: True
Explanation:
For plotting a point, we need two coordinates, the x coordinate and the y coordinate.
A line graph can also be a whole unbroken line.
Solution: False
Explanation:
A graph which has whole unbroken lines is called a linear graph.
The distance of any point from the x-axis is called the x-coordinate.
Solution: False
Explanation:
The distance of any point from the x-axis is called the y-coordinate
The distance of the point (3, 5) from the y-axis is 5.
Solution: False
Explanation:
The distance of the point (3, 5) from the y-axis is 3 and from x-axis is 5
The ordinate of a point is its distance from the y-axis.
Solution: False
Explanation:
The ordinate is also known as the y-coordinate, where it is defined as a distance from the x-axis
