    Hi i would like to know whether i am going in the right direction in solving this problem.

    Question: To produce a batch of electronic components involve a fixed cost of $600. Labour and material amount to $2 per component.

    (i) Write the linear equation to represent the total production cost Y, in terms of the number of components produced.
    (ii) Represent the equation by drawing a graph assuming any 5 values for X.
    (iii) Use the graph to find the number of components produced if the total cost is $1500.


    So answering the first question 2x + 600 = Y (is this correct )

    Please help

    Thank you

    Yes this is correct. You should have no problems now answering points (ii) and (iii).
