Answer:

$Y = ( -1) | 8 | 17 | 26 | 35|$

Step-by-step explanation:

$y = 9x + 8 \\ \\ \\ x = ( - 1) \\ y = 9( - 1) + 8 \\ y = - 9 + 8 = - 1 \\ \\ x = 0 \\ y = 9(0) + 8 \\ y = 0 + 8 = 8 \\ \\ x = 1 \\ y = 9(1) + 8 \\ y = 9 + 8 = 17 \\ \\ x = 2 \\ y = 9(2) + 8 \\ y = 18 + 8 = 26 \\ \\ x = 3 \\ y = 9(3) + 8 \\ y = 27 + 8 = 35 \\ \\ \\ Y = ( - 1) | 8 | 17 | 26 | 35|$
