NCERT Solutions For Class 9 Math Chapter – 3 Exercise – 3.2
Q1. Write the answer of each of the following questions:
- What is the name of horizontal and the vertical lines drawn to determine the position of any point in the cartesian plane ?
- What is the name of each part of the planes formed by these tow lines?
- Write the name of the point where these two lines intersect
Solution:-
- The horizontal line: x – axis and the vertical line: y – axis
- Each part is called “Quadrant”
Q3. See the given figure and write the following:
- The coordinate of B.
- The coordinate of C.
- The point identified by the coordinate (-3,-5).
- The point identified by the coordinate (2,-4)
- The abscissa of the point D.
- The ordinate of the point H.
- The coordinate of the point L.
- The coordinates of the point M.
Solution:-
From the figure , we have
- The coordinate of B are (-5,2).
- The coordinated of C are (5,-5).
- The point E is identified by the coordinates (-3.-5).
- The point G is identified by the coordinates (2,-4).
- The abscissa of the point D id 6.
- The ordinate of the point H is -3.
- The coordinate of the point L are (0,5)
- The coordinates of the point M are (-3,0).
