Question (a)
The relationship between satisfaction score and salary is a positive one. The graph shows a positive correlation. It means, the higher the salary, the higher the satisfaction score
Question (b)
We will substitute the value of

into the equation

Question (c)
The constant 0.0005 is the increase of satisfactory score by 0.0005 for every pound increase in the salary
To solve for n you have to get n on one side of the equation by itself.
n-6m=8
take -6m and add to both sides. so the side that has n evens out to 0. then you have
n=6m+8
it is this way because you can only add like terms. This should be all you need to do.
Hope this helps
