A dog trainer charges an initial consultation fee plus an additional hourly rate for obedience training. The graph shows the total cost for the consultation and hourly rates. Find and interpret the rate of change (price per hour) and initial value (y-intercept) *

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

the answer is c.
