Step-by-step explanation:
The equation of the line is given as

A straight line equation is given in the form

where

is the gradient and

is the y-interest.
We need to rearrange

to make

the subject.

⇒ from here we can read the gradient and the y-intercept. The gradient,

and

<span>A line that is parallel to

will have the same gradient,

but different y-intercept. One example of equation of a line that is parallel to

is

Answer:
The first choice is correct.
Step-by-step explanation:
First work out the common ratio r:-
a2 = a1r and a5 = a1 r^4
So r^3 = a1r^4 / a1r = 256/ 108
r = cube root (256/-108) = 4/3
So the explicit formula is 108(4/3)^(n-1)
