Question

one spring day, yusuf noted the time of day and the temperature, in degrees fahrenheit. during that time, the temperature rose, stayed steady, and fell, at different rates. on the set of axes below, yusuf created a graph of temperature over time. at what rate did the temperature rise from 6 a.m. to 8 a.m.?

Explanation:

Step1: Identify points

At 6 a.m., temp is 58°F; at 8 a.m., temp is 66°F.

Step2: Calculate rate

Rate = $\frac{\text{Change in temp}}{\text{Change in time}}=\frac{66 - 58}{8 - 6}=\frac{8}{2}=4$ °F per hour.

Answer:

4 degrees Fahrenheit per hour
