Question

The temperature at sunrise is 65 degreesF. Each hour during the day, the temperature rises 5 degreesF. Write an equation that models the temperature y, in degrees Fahrenheit, after 4 hours during the day.

Answer 1

now: temp = 65
after 1 hour temp = 65 + 5(1)
after 2 hours temp = 65 + 5(2)
after 3 hours temp = 65 + 5(3)
...
after x hours temp = 65 + 5x

Answer 2

The tem perature at sunrise is 65°F. Each hour during the day, the
tem perature rises 5°F. Write an equation that models the tem perature y, in degrees
Fahrenheit, after x hours during the day. What is the graph of the equation?
