While hiking, Devon's altitude rose 10 feet for every 5 minutes. After an hour of hiking,
his altitude was 295 feet. Assume the relationship is linear. Find and interpret the rate of change and initial value.

rate of change = 2 ft /min

initial value = 175 feet elevation

Step-by-step explanation:

we are given that his altitude rose 10 feet for every 5 min,

hence the rate of change

= 10 feet ÷ 5 min

= 2 feet/min

we are also given that he hiked for an hour and ended up at 295 feet

1 hour = 60 min.

for a rate of 2 feet / min, if he walked 60 min, he would have walked:

2 feet/min x 60 min = 120 feet.

final value = initial value + change

initial value = final value - change

= 295 - 120

= 175 feet elevation

it is probably the graph on the bottom right.
