Mark starts a rock climb when he is 1 mile above sea level. he can climb at the rate of 1.5 miles per hour. which of the following functions would express mark's height above sea level over time

The required function which represent the Mark's height above sea level over time is

Step-by-step explanation:

Given : Mark starts a rock climb when he is 1 mile above sea level. He can climb at the rate of 1.5 miles per hour.

To find : Functions would express Mark's height above sea level over time?

Solution :

Let x be the time in hours and y is the height of Mark's.

The the linear function form,

Where, b is the initial value or distance he cover,

b=1 mile

m is the slope or rate at which he climb,

m=1.5 miles per hour.

Then the linear function is

Therefore, The required function which represent the Mark's height above sea level over time is

im alright what do you need
