Question 1047538: Cost to produce 17 toys is $731 and cost of 29 toys is $1247. If cost is considered to be c, and is a linear relation to an output qty, marked by q, find the cost equation. Am I right this is will be considered to be a function and we mark it as c(q)? How do I then solve this?

Two linear points, (q,c) are (17, 731) and (29, 1247). Function is c(q).

c=mq%2Bb, slope m, vertical axis intercept b.

c-mq=b
b=c-mq

Pick one of the given or described points:
c=%28%281247-731%29%2F%2829-17%29%29q%2B%28731-%28%281247-731%29%2F%2829-17%29%29%2A17%29
Simplify this equation or function definition.
