Question 476271: The cost of driving a car includes both fixed costs and mileage costs. Assume that it costs $164.30 per month for insurance and car payments and $0.35 per mile for gasoline, oil, and routine maintenance.
(a). Find values for m and b so that y = mx + b models the monthly cost of driving the car x miles.
(b). What does the value of b represent?

You can put this solution on YOUR website!
+y+=+mx+%2B+b+
x = miles driven/month
y = total monthly cost of driving car
b = all fixed monthly costs that do not depend on the miles driven
---------------
given:
m+=+.35
+b+=+164.30+
The equation is:
+y+=+.35x+%2B+164.3+
