QUESTION 1 1.1.
A quadratic pattern has a second term equal to 1, a third term equal to -6 and a fifth
term equal to -14.
(5)
1.1.1. Calculate the second difference of this quadratic pattern.
(2)
1.1.2. Hence, or otherwise, calculate the first term of the pattern.​

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.

i believe that the answer is

b. y-1=-2(x-4)

hope this !
