Question 883676
First option: 2200 +115a = final cost, where a is the number of years.
Second option: 3550 = final cost
There is no variable in the second option, and therefore not a linear relationship.
In the first option, if we plotted this on a graph, we would BEGIN at 2200 and then rise 115 each year.  This creates a line.  The line does not begin at zero, but it is still a linear equation, just starting at the fixed cost.
