Laura hiked up lamb's canyon i 2 hrs and then ran back down in 1hr. her speed running downhill was 2.5 mph faster than her speed hiking uphill. how far up the canyon did she hiked

{3 + i, 3 - i, 3, -1}

step-by-step explanation:

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
