Question

he temperature at sunrise is 40degreesF. Each​ hour, the temperature rises 5degreesF. Write an equation that models the temperature​ y, in degrees​ Fahrenheit, after x hours. What is the graph of the​ equation?

Answer 1

Answer:

$y=40+5x$

The graph is shown below.

Step-by-step explanation:

Given:

Initial temperature is, $T_{0}=40$°

Rise in temperature per hour is 5°

Therefore, rise in temperature after $x$ hours is $5x$.

According to question, temperature, $y$ is given as :

$y=40+5x$.

Now, the graph is shown below.

The slope of the graph is 5°per hour and $y$ intercept is 40.
