A hiker climbed down a 75-foot hill in six minutes. What is his average change in elevation per minute? A.450 feet per minute

B.-450 feet per minute

C.12.5 feet per minute

D.-12.5 feet per minute

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

yes the data was not prsented
