at midnight the outside temperature is 10 degrees fahrenheit. by 4:00 am the temperature is -2 degrees fahrenheit. show the equation to determine the average change in temperature per hour

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )

f(x)=4
