I’ve always thought these kind of questions can ‘trick’ you at first, because you realise that it’s actually more a simultaneous equation type question, and not a graph question. See that you have 4 unknowns, and information to form equations. The key piece of information to this question is probably the line about the property of it being symmetrical about the y-axis, which you can actually use the info to form two more equations with :)
