Answer:
A. y = x - 3
Step-by-step explanation:
By examining the table, we can see that all y-values have a constant correlation to each x-value by -3. Therefore, the best answer is y = x - 3.
x + 3 would change to y-values to 7, 9, 11, 13.
4x would change the y-values to 16, 24, 32, 40.
x + 2 would change the y-values to 6, 8, 10, 12.
hope this helps!
