Write an expression for the total cost of each hotel if n represents the number of nights he will stay.
holiday inn: $80 a night plus $10 for parking
days inn: $110 a night with a $50-off coupon

so what is the question

step-by-step explanation:

the first one, all those points on the line just make a strait line.

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
