Take the equation: y = 520 + 14x and put each value from the table in for x and y.
100 = 520 + 14 * -30 100 = 520 + -420 100 = 100 When we get an answer like this where the numbers on both sides of the equation match, we know that this (x,y) point is a part of the solution to the function.
So, you would work through each line in the table. If they are all like the one above, the answer is Yes. If not, it is no.
