Question

Among the following points, not lie on the line x + y = 7 is
A)(2,5)
B)(3,4)
C)(4,3)
D)(6,-1)​

Answer 1

Answer:

option D is Correct

Step-by-step explanation:

Given,

X+Y=7

Further Check The Options,

A:(2,5) X=2,y=5

Substitute in Given,

2+5=7 i.e.,it's true

B:3+4=7✓

C:4+3=7✓

D:6+(-1)=7

6-1=7

5 Is not Euals to 7

That's why The Answer is Option D

Answer 2

Answer:

$(6,-1)$

Step-by-step explanation:

If any point lie on the line than its satisfy the equation $x+y=7$.

Now, take first point (2,5)

$x+y=2+5=7$

Since first point satisfy the equation. then (2,5) is lies on the line $x+y=7$.

Now, take second point (3,4)

$x+y=3+4=7$

Since second point satisfy the equation. then (3,4) is lies on the line $x+y=7$

Now, take third point (4,3).

$x+y=4+3=7$

Since third point satisfy the equation. then (4,3) is lies on the line $x+y=7$

Now, take fourth point (6,-1).

$x+y=6+(-1)=5$

Since fourth point (6,-1) is not satisfy the equation $x+y=7$.

Therefor (6,-1) not lies on the line $x+y=7$.
