Answer:

y intercept is 18

Explanation:

It is given that

Monthly rent for phone service = $18

charges for each long distance minute = $ 0.07

Let us assume number of minutes used = x

also let us represent total cost by y

So the total cost = ( charges per minute )(number of minutes) + monthly rent


y= 0.07x+18

now we compare this equation with y=mx+b

where m is the slope and b is y intercept

so we have b= 18

hence y intercept is 18
