The point (4,1) and (x,-6) lie on the same line. If the slope of the line is 1, what is the value for f x?

-3

Step-by-step explanation:

slope= y2 - y1 / x2- x1

where y2=-6

y1= 1

x2=x

x1= 4

slope=1. , substitute into formular

1= -6-1/x-4

1= -7/ x-4. Cross multiply

x-4=-7

x= -7+4

x=-3

-2

7 - 9 = -2

reversed:

-2 + 9 = 7

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.
