The cost is given as
[tex]10+0.5x[/tex]
Where x is the number of hours
The y-intercept is obtained from the graph as shown below
The value of the y-intercept is obtained to be 10
The y-intercept represents the value represents the fixed cost.
The slope of the cost is obtained from the cost function to be 0.5.
The slope represents the change in cost with respresent to time (hour).
Hence,
lank 1: 10
Blank 2: The fixed cost
Blank 3: 0.5
Blank 4: Change in cost or charge with respect to time used in hours
Blank 5:
[tex]C=10+0.5h[/tex]
