Explain why the slope is not the same as the first differences. |
| | A) | The slope is not the same as the first differences because the x-values increase by a constant factor of 2. |
| | B) | The slope is not the same as the first differences because the y-values increase by a constant factor of 3.. |
| | C) | The slope is not the same as the first differences because the relation is non-linear. |
| | D) | The slope is not the same as the first differences because the relation is linear. |

| | A) | F = 15t – 20 |
| | B) | F = 15t + 20 |
| | C) | F = 20t – 15 |
| | D) | F = 20t + 15 |
