Question

Give the geometric representation of 2x + 5 = 0 as an equation

(i) In one variable
(ii) in two variables .​

Answer 1

Step-by-step explanation:

Given:2x+5=0

To find: Give the geometric representation of 2x + 5 = 0 as an equation

(i) In one variable

(ii) in two variables

Solution:

(i) In one variable:

2x+5=0

$2x = - 5 \\ \\ \bold{x = \frac{ - 5}{2}}$

See 1st attachment.

(ii) In two variable:

2x+0.y+5=0

Independent of value y,the value of x always remains same.

$( \frac{ - 5}{2} ,0) \\ \\ ( \frac{ - 5}{2}, 1) \\ \\ ( \frac{ - 5}{2} ,2) \\ \\(-2.5,0),(-2.5,1),(-2.5,2)...$

and so on.

See second attachment.

Hope it helps you.
