It has been found that the supply of golf clubs varies linearly with its price. When the price per item was
$ 76.00 ,32 items are supplied;
When the price was $ 90.25 , 70 items are supplied.
What is the lowest price above which golf clubs will be supplied ?
So I know the slope is 14.25/38. And I'm guessing I'm going to have to find the minimum of something and use -b/2a. But I'm having trouble coming up with the right quadratic equation to use..
Nevermind, now I see that all the question asks for is the y-intercept. Why didn't I see that before...
