One spring day, Landon noted the time of day and the temperature, in degrees Fahrenheit. His findings are as follows: At 6 a.m.,
the temperature was 50° F. For the next 3 hours, the temperature rose 4° per hour. For the next 4 hours, it rose 1° per hour. The temperature then stayed steady until 6 p.m. For the next 2 hours, the temperature dropped 2° per hour. The temperature then dropped steadily until the temperature was 58° at midnight. On the set of axes below, graph Landon's data.
Slope formula is the difference of the y values divided by the difference of x values. Choose to points. I chose (-2,-1) and (0,3). 3-(-1) is equal to 4. 0-(-2) is equal to 2. 4 divided by 2 is two.
