Emily is 280 miles away from home. She is traveling back at a rate of 40 miles per hour. Determine which graph and which equation represent Emily's distance from home, D, after Emily travels h hours.

-40*h+280

Step-by-step explanation:

Let's define the function f which represents Emily's distance from home at h = 0 Emily is 280 miles away from home

so f(0)=280

as she is traveling back at a rate of 40 miles per hour

f(h)=-40*h+280

10 * 563.67 = 5636.7
