Answer:
y = 3x -8
Explanation:
You can try a point in the function rules and see if it works. The first (x, y) pair is suitable for finding the right answer:
y = -3(-3) -8 = -1 ≠ -17 . . . . eliminates the first choice
y = 1/3(-3) -8 = -9 ≠ -17 . . . . eliminates the second choice
y = 3(-3) -8 = -17 . . . . . the third choice is viable
y = 1/3(-3) +8 = 7 ≠ -17 . . . . eliminates the last choice

Only the third choice is a possible solution. Checking other points from the table verifies this as the correct one.
