If a dental patient is charged $65.97 for teeth cleaning, $127.12 for x-rays, and $94.50 for a dental exam, what should his total bill be for the procedures

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

answer: the answer is fre sha voca do
