Question

Please help me with this

Answer 1

The two end points of our line are (0,2.5) and (5,5.5). to find our slope we need  to find our n difference (higher value - lower value) and our C difference (same as n) which would be 5 and 3. now we put our cost difference over our miles difference and get our slope (5/3). this means we still need out starting point. which is a cost of 2.5. the equation is C = (slope)5/3n + (starting value)2.5

Answer 2

C starting value is 2.5
