Question

Please explain how to do this

Tim began a hike near Big Bear Lake,
California at the base of the mountain that is 7000 feet
above sea level. He is hiking at a steady rate of 5 more
feet above sea level per minute. Let A be his altitude
above sea level in feet and let t be the number of
minutes he has been hiking. Write an equation in
slope-intercept form that represents how many feet
above sea level Tim has hiked.​

Answer 1

Answer:

  A = 5t +7000

Step-by-step explanation:

Tim's rate of increasing altitude is 5 ft/min, so his change in altitude in t minutes is 5t.

If he started at 7000 ft, his altitude as a function of time is the sum of his initial altitude and his change in altitude:

  A = 5t +7000
