Let us work out – 3.1
Question 1
I plot the following points on graph paper and write the points that lie above or below the x-axis.
(3,-2), (-4,2), (4,5), (-5, -5), (-2, 7), (7, -7), (0,9), (0,-9)
Solution:
The point above / below of x-axis | |
(3,-2) | below |
(-4,2) | above |
(4,5) | above |
(-5,-5) | below |
(-2,7) | above |
(7,-7) | below |
(0,9) | above |
(0,-9) | below |
Question 2
I plot the following points on graph paper and write the zero points to the right or left of the y-axis.
(5,-7), (10,10), (-8,-4), (4, 3), (-6, 2), (11,-3), (4,0), ( -4,0)
Solution:
Point of y-axis | |
(5,-7) | right |
(10,10) | right |
(-8,-4) | left |
(4,3) | right |
(-6,2) | left |
(11,-3) | right |
(4,0) | right |
(-4,0) | left |
Question 3
I plot the following points on graph paper and write their positions (In which quadrant or on which axis and in which direction)
(-11,-7), (0,5), (9,0), (-4, -4), (12,-9), (3,13), (0,6), (-5,0)
Solution:
(-11,-7) → 3rd quadrant.
(0,5) → on the positive y-axis
(9,0) → on the positive x-axis.
(-4,-4) → 3rd quadrant.
(12,-9) → 4th quadrant.
(3,13) → 1st quadrant.
(0,-6) → on the negative y-axis
(-5,0) → on the negative x-axis
Question 4
Let us write the coordinates of any four points on the x-axis.
Solution:
The coordinates of any four points on the x-axis are (6,0), (12,0), (-5, 0), and (-9,0).
Question 5
Let us write the coordinates of any four points on the y-axis.
Solution:
The coordinates of any four points on the y-axis are (0,5), (0,7), (0,- 3), and (0,-7).
Question 6
Let us find any point on each quadrant. Write the coordinates of the four points.
Solution:
(3,2) → 1^{st} first quadrant.
(-2,4) → 2^{nd} Second quadrant:
(-2,-3) → 3^{rd} third quadrant.
(3, -4) → 4^{th} Fourth quadrant.
Question 7
The distance of a point from the x-axis is 5 units and from the y-axis is 7 units. Let us write the coordinates of the point.
Solution:
The Co-ordinates of the point = (5,7)
