    And since it is nearly always the extreme points of the regions, I tried all three. Two were obviously useless (y=0...), and the top one gave 14. I did not take it any further than this. There are ways it can be checked, but I am very, very lazy...

    oh yeh did the top oen two but ended up with 18 dont no how i managed that but aybe marks for subsitution. what was the line again 2x and 3y equals 18?

    What was question 10 and how did it involve simultaneous equations.. I can't remember.
    "Find the coordinates of the points of intersection of the line y = 5 - 2x with the curve y = x^2 - 4x - 11, giving your answers correct to 2 decimal places."

    I forgot to find the y coordinates.
