Q-2 Give the geometric representation of as and equation,

  1. in one variable

  2. in two variables.

Solution:

Equation of in one variable

The representation of on the number line is as show below:

Give geometric representation of given equation for one variable

Give Geometric Representation of Given Equation for 2x+9=0

Give geometric representation of given equation for one variable

  • In two variable can be written as

    It is a linear equation in two variable and . It is best to represent this line on a plane- the coordinate plane. Note that all the values of are permissible because is always . However, must satisfy the relation . That is, y- coordinates of the points on this line don’t matter as long as their x-coordinate . Understood this way, it is a line parallel to y axis passing through x =

  • Two possible points on this line can be

  • So plotting point and joining them we get the graph AB as a line papallel to at a distance of on the left .
