RE the point below from Aiden, this is OK, it is giving the student the opportunity to explore the terms in the equation and how they relate to the graph. This sort of question is really for formative use.

Good work making use of the extension. I have removed some of the unused variables, which Christian was mainly including for demo purposes.

Elliott, can you add a step to both parts please, giving the formula and asking the student to identify $a_1$ and $d$
