Have you made any attempt at these questions? How far have you got?

Both of these need to be in the form y = mx + c (or whatever symbols you're using for "gradient" and "y-intersection" - m and c are what I'm using, respectively).

So here are two further sub-questions that will get you started on the first question:

i) What is the gradient (m in the equation above) of the first line?

If you can answer this, you'll have the m in the equation. Then:

ii) What does c have to be so that y = 2 when x = 7?

Get back with any thoughts/answers/guesses (:P) you have for these.
