Paper 2 Question 11 - Linear Programming

Here are the notes on Linear Programming:

Introduction - here and here
Looking at part a) half-planes
Worked example of a part b).

NB: when answering part b) (i) which is usually "write down two inequalities in x and y and illustrate these on graph paper" you must
a) use graph paper and
b) shade in the region which represents all the inequalities (including x≥0 and y≥0) or at least indicate the half planes with arrows. If you just draw the lines you could lose 3 marks per inequality ... or 1%!
