Question

IT WOULD BE HELPFUL IF YOU GUYS CAN HELP ME WITH THIS!

The temperature at sunrise is 28°F. Each​ hour, the temperature rises 7°F.

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

Answer 1

28=(7)x+b

Explanation:

y=mx+b right?

starts at 28, so plug that into y

28=mx+b

the rate of change is 7, so you plug that into m

28=(7)x+b

(I'm sorry if this is wrong, this is just my understanding of this)

Answer 2

y=6x+24

Explanation:

your temperature at the y-intercept is 24 degrees, and your slope being 6/1, so that would be your line equation. You can just plug in to solve after that

Remember that for your graph your dependent variable is always on the x-axis, and your independent variable is always on the y-axis. So because the temperature depends on time, the x-axis is the time of day in hours, and your y-axis is the temperature in Fahrenheit.
