Step-by-step solution for: Math Worksheets | Dynamically Created Math Worksheets
Let's solve each function table step by step. We'll plug in the given $ x $-values into the corresponding equation to find the $ y $-values.
---
| $ x $ | $ y = \frac{1}{6}x + 6 $ |
|--------|---------------------------|
| 3 | $ \frac{1}{6}(3) + 6 = 0.5 + 6 = 6.5 $ ✔ |
| -1 | $ \frac{1}{6}(-1) + 6 = -0.1667 + 6 = 5.8333 $ ✔ |
| 6 | $ \frac{1}{6}(6) + 6 = 1 + 6 = 7 $ ✔ |
| -9 | $ \frac{1}{6}(-9) + 6 = -1.5 + 6 = 4.5 $ ✔ |
| 1 | $ \frac{1}{6}(1) + 6 = 0.1667 + 6 = 6.1667 $ (given as 6.167) ✔ |
✔ Already correct.
