let x be 0

y=40

x be 1

x=39

x be 2

x=38 hope it is helpfulll....:)

Step-by-step explanation:

Answer 2

$\huge{\underline{\underline{\bf{\purple{✿Question:-}}}}}$

Represent x+y = 40

$\huge{\underline{\underline{\bf{\red{✿Required\: Answer:-▼}}}}}$

[. To represent x+y = 40, we have to find out it solution and then we can represent it.]

${\underline{\bf{\green{Finding\: solution\:of\:x+y=40}}}}$

✪Let x = 20,

Now, put the value of x in x+y = 40

20+y = 40

=> y = 40-20 = 20

First solution = (20,20)

✪ Let x = 25

Now, put the value of x in x+y = 40

25+y = 40

=> y = 40-25 = 15

Second solution = (25,15)

✪Let x = 30

Now, put the value of x in x+y = 40

30+y = 40

=> y = 40-30 = 10

Third solution = (30,10)

${\underline{\bf{\green{To\: Represent}}}}$

(20,20), (25,15),(30,10)

This is represented in the given picture.

Note :- We we represent this equation, then it's representation always gives straight line.
