Question

Give the geometric representations of 2 x + 9 = 0 s an equation.

(i) In one variable

(ii) 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).

Hope it will help you. Thank you.

Answer 2

Answer:

equation

Step-by-step explanation:

2x+9=0

2x = - 9

X = - 9/2

X = 4•5

therefore, the answer is 4•5.

(ii) in two variables
