Question

The temperature at sunrise is 40°F. Each​ hour, the temperature rises 4°F. Write an equation that models the temperature​ y, in degrees​ Fahrenheit, after x hours. What is the graph of the​ equation?

Write an equation that models the temperature​ y, in degrees​ Fahrenheit, after x hours.

Answer 1

y = 4x + 40

Explanation:

At sunrise, 0 hours have passed, meaning x = 0.

When x = 0, the temperature is 40, meaning that 40 is the y-intercept.

And every x hours the temperature rises by 4 degrees F
