a phone company charges for service according to the formula: C(n)=25+0.02n, where n is the number of minutes talked and C(n) is the monthly charge, in dollars what is the slope?

which expression represents the approximate length of bc?

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

yes

step-by-step explanation:

yes
