To solve the equation [tex]\( x + y = 8 \)[/tex] for [tex]\( y \)[/tex] given that [tex]\( x = -1 \)[/tex], follow these steps:

1. Substitute [tex]\( x = -1 \)[/tex] into the equation [tex]\( x + y = 8 \)[/tex]:
[tex]\[ -1 + y = 8 \][/tex]

2. To isolate [tex]\( y \)[/tex], add 1 to both sides of the equation:
[tex]\[ -1 + y + 1 = 8 + 1 \][/tex]

3. Simplify the left side of the equation:
[tex]\[ y = 8 + 1 \][/tex]

4. Perform the addition on the right side:
[tex]\[ y = 9 \][/tex]

Therefore, the value of [tex]\( y \)[/tex] is [tex]\( 9 \)[/tex].
