Here is the problem I am working on..
Lynn found in May her driving cost was $390 for 760mi and in June her cost was $410 for 800mi. Assume there is a linear relationship between the monthly cost C of driving a car and the distance driven d. Find a linear equation that relates to C and d.
After the equation is written I'll have to graph it and then use it to predict other costs. I can do both of those but only once I figure out how to set up the original equation.
I would like to do as much of the work as possible so if someone could please help me get started or give me some information on how to do this it would be very much appreciated.
Thanks!
