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).
