I did the first part how would i graph it.

Problem:

Business and finance. The cost of 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 and the variable cost is $10, write the cost equation.

(b)Graph the cost equation.

My answer:

For (A) C = 10x + 40

FOr (B) how do i graph this?

graph it like a normal line in y=mx+b form. it has a slope 10 and y-intercept of 40.

i wasn't sure if that's how i was suppost to look at it. thanks so much.
