what you can do for the table questions plug in the numbers, for example in number 1 one of the equations is y=4x-6 in the x part you can put -1 so what you do now is y=4(-1)-6 so the answer would be equals -10 so that would equal your you answer. You keep doing it until one answer isn't like the other then you move on to the next equation if it doesn't match. Hope this helps a bit.
