1. The cost of owning a car is linearly related to the number of kilometers driven. A driver has tracked costs over many months and has found the following linear relation, C = -x+ 260 5 12 where C is the monthly cost in dollars and x is the number of km driven in that month. a) The linear relation is in slope-intercept form. By inspection only, interpret the equation and state the slope and the C-intercept: Explain, using units, the meaning of each of these parameters in this problem context. b) What is the practical domain for this linear model?
