Unfortunately the answers to this one are all messed up, so do work it yourself first (unless it gets updated!).
The graphs are not super accurately plotted, but (from the given equations) there are three pairs of identical ones: 1 & 14, 3 & 6, and 8 &11. The given answers 1-3 are correct, but then answers 4 to 12 are actually solutions for 5 to 13. The answer for 4 is 4x-2y=0 (the penultimate equation in the grid). Answer 15 is the answer to 16. Answer 16 is the answer to 14. Answer 14 is the missing equation (for graph 15). Answer 14 is not an equation from the grid. The missing graph is for -3y-2x=-6 (right-hand side, penultimate row in the grid) -- the supplied answer graph is not correct.
