Find x so that the two points are on the line with the given slope (1,-1) and (x,7): undefined

Value of x for which the two points are on the line with the given slope (1,-1) and (x,7): undefined is .

Step-by-step explanation:

Here we have to Find x so that the two points are on the line with the given slope (1,-1) and (x,7): undefined . Let's find out:

We know that for any two points given as  slope of line is determined by :

⇒

According to question we have two points as   ∴

⇒

⇒

But slope is undefined which is only possible when denominator is zero i.e.

⇒

⇒

Therefore , Value of x for which the two points are on the line with the given slope (1,-1) and (x,7): undefined is .

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
