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

`y=40+5x`

The graph is shown below.

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.
