The change in minutes for every change of one degree Fahrenheit.

Answer 1

In Fabian's equation \( y = 50x + 78 \), the term "50" represents the rate of change in the oven's temperature over time. This means that for each minute (each unit increase in \( x \)), the temperature increases by 50 degrees Fahrenheit.

So the correct answer is:

**The rate of change in the oven's temperature over time.**
