Hi,
A table of values is a set of numbers that could be equal to x and a set of values that could be equal to y. This is pre-algebra, I'm guessing, so you could solve it this way:
y = x - 6
So what would happen if x was 3? It would be y = 3 - 6, which would be -3.
What would happen if y was 4? Y = 4 - 6, which is -2.
If y was 5? 6? 7?
You take all these "what if's" and put them in a chart, like below. That's called a "table of values" :)
