Question

For a science experiment, Claudia observes the effects of temperature on a substance. The original temperature is 9°C, and Claudia increases the temperature by 2°C each hour. Then Claudia graphs the relationship between time and temperature. What is the y-intercept of Claudia’s graph and what does it represent?

Answer 1

Answer:

The drop in temperature is 42-(-54)=42+54=96℉. Rate of drop is 12℉. So it will take 96/12=8 hours.

Another way: -54-42=-96, -96/-12=8 hours.
