Final answer:
To find the missing y-value when x is 8 in the equation y = 9 + 3x, substitute 8 for x and solve for y, which results in y=33.
Step-by-step explanation:
The question asks for the missing y-value corresponding to x=8 for a linear equation. Given the equation y = 9 + 3x, we can find the y-value by substituting x with 8. Here is a step-by-step calculation:
- Start with the equation: y = 9 + 3x.
- Substitute x with 8: y = 9 + 3(8).
- Multiply 3 by 8 to get 24: y = 9 + 24.
- Add 9 and 24 to get 33: y = 33.
Therefore, the missing y-value when x is 8 is 33.
