Question

Give the geometric representations of 2x + 9 = 0 as an equation
(i) in one variable
(i) in two variables
​

Answer 1

Step-by-step explanation:

(i) In one variable

Given equation is 2x+9=0

⇒2x=−9

⇒x=

2

−9

=−4.5

(ii) Given equation is 2x+9=0

⇒2x+0y+9=0

⇒2x=−9

⇒x=

2

−9

=−4.5

It is line parallel to y-axis at a negative distance.

Two points lying it are the points A(−4.5,0),B(−4.5,2).
