(1) Write the name of the point where these two lines intersect
2. See Fig.3.14, and write the following:
(1) The coordinates of B.
(ii) The coordinates of C.
(i) The point identified by the coordinates (-3,-5).​

Answer 1

Answer:

1.

1. The name of horizontal and vertical lines drawn to determine the position of any point in the Cartesian plane is x-axis and y-axis respectively.
2. The name of each part of the plane formed by these two lines x-axis and y-axis is quadrants.
3. The point where these two lines intersect is called the origin.

2.

1. The co-ordinates of B is (−5, 2)
2. The co-ordinates of C is (5, −5).
3. The point identified by the coordinates (−3, −5) is E.

Answer 2

Question :-

Write the answer of each of the following questions:

(i)What is the name of horizontal and the vertical lines drawn to determine the

position of any point in the Cartesian plane?

(ii) What is the name of each part of the plane formed by these two lines?

(iii) Write the name of the point where these two lines intersect.

Answer :-

(i)    The name of horizontal lines and vertical lines drawn to determine the position of any point in the Cartesian plane is x-axis and y axis respectively.

(ii)    The name of each part of the plane formed by these two lines x-axis and y-axis is called as quadrants (one fourth part)  

(iii)    Name of the point where there two lines intersect is called as origin.
