: The cost of the producing a number of items x is given by C=mx+b, in which b is the fixed cost and m is the variable cost (the cost of producing one more item).
a). If the fixed cost is $40.00 and the variable cost is $10.00, write the cost equation.
b). Graph the cost equation.
The equation I came up with is C=10x+40. However I have not a clue on if this is correct and how to graph this equation. Could you please give some assistance. Thanks.This question is from textbook Beginning Algebra

The cost of the producing a number of items x is given by C=mx+b, in which b is the fixed cost and m is the variable cost (the cost of producing one more item).
a). If the fixed cost is $40.00 and the variable cost is $10.00, write the cost equation.
b). Graph the cost equation.
The equation I came up with is C=10x+40.
You're right about the equation, so give yourself a high five!
To graph this, give yourself a scale of 1 unit per 10. (Just count by tens)
Plot a point on the y axis at 40, then use the slope, m=rise/run, go up 10 and right 1 and plot another point at (1,50). Connect the points and you have a line.

Happy Calculating!!!
