If you are Year 10 or 11 then yes. You will have done the difference of two squares when you did quadratics: multiplying out 2 brackets, and factorising quadratics. Have a look here: http://www.mathsteacher.com.au/year10/ch10_factorisation/03_dots/dots.htm 2nd question - yes if you are year 11. If you are year 10 look at the revision list you were given in class rather than the guide. JT Hi Emma,

10 squared is 10×10 which is 100 so multiply 2.1 by 100.

Put values in: if x = 0, then y = 0.5 x 0 which = 0, so the line goes through the origin. Sophie, 0.5 is the gradient!
