Question

The values in the table represent a linear function. How does the value of y change in relation to a change in the value of x?

A) for every change in x by -6, y changes by 4


B) for every change in x by 6, y changes by -4


C) for every change in x by -4, y changes by -6


D) for every change in x by -6, y changes by -4

Answer 1

Answer: Choice A) for every change in x by -6, y changes by 4

In other words, each time x goes down by 6, y goes up by 4. We see this when we move from any given row to the next row down below it. For instance, from row 1 to row 2 we have x = 9 drop to x = 3 (a drop of 6); at the same time, we have y = 4 increase to y = 8 (increase of 4).
