Question

give the geometric representation of 2 X + 9 is equal to zero as an equation i) in one variable ii) in two variables​

Answer 1

(i). in 1 variable

2x + 9 = 0

$x = \frac{ - 9}{2}$

x = - 4.5

(ii). in 2 variables

2x + 0y + 9 = 0

Here , in this equation we have to put different values of y such as 0 , 1 , -1 , etc...

then , we have solution like -

• when y = 0 , x = - 4.5
• when y = 1 , x = - 4.5
• when y = -1 , x = - 4.5

similarly for whatever value of y , x remains same as - 4.5

now we can plot it on graph

Answer 2

Answer:

2x + 9 = 0

x = \frac{ - 9}{2}x= 2 −9

x = - 4.5

(ii). in 2 variables

2x + 0y + 9 = 0

Here , in this equation we have to put different values of y such as 0 , 1 , -1 , etc...

then , we have solution like -

when y = 0 , x = - 4.5

when y = 1 , x = - 4.5

when y = -1 , x = - 4.5

similarly for whatever value of y , x remains same as - 4.5

now we can plot it on graph
