    http://prnt.sc/b7z6px <-- This is the question, I am unsure on how to do part b) of it...

    Here's the solution but I do not seem to understand why 8^2 was calculated?

    So the question states that 1 unit on each axis represents 8cm (rather than 1 as assumed previously), therefore the area in part a will need to be multiplied by 8^2 as both the x and y values have been increased by 8.
Do you agree with the PM's proposal to cut tuition fees for some courses?
