Solve the problem.
-The cost of manufacturing a computer part is related to the quantity produced, x, during a production run. When 100 parts are produced, the cost is $300. When 600 parts are produced, the cost is $4800. Find an equation
Of the line relating quantity produced to cost. Write the final answer in the form C = mx + b.
A) C = 9x
B) C = 9x - 600
C) C = 9x + 600
D) C = 600x + 9

The slope (m) is calculated as (4800 - 300) / (600 - 100) = 9. Using the point (100, 300) to find b: 300 = 9(100) + b, so b = -600. Thus, the equation is C = 9x - 600.
