Answer:
The y-intercept is y = -$150
Step-by-step explanation:
We know that:
Each necklace is sold for $8.
The total cost for Michelle is $150.
The profit equation is:
Profit = Revenue - Cost.
We already know that Cost = $150
The revenue will depend on x, the number of necklaces sold, so if each one costs $8, and she sells x of them, the revenue is:
Revenue = $8*x
Then the profit, as a function of x, is:
y = P(x) = $8*x - $150
Where y represents the profit.
Now we want to find the y-intercept of the profit equation, where the y-intercept is the y-value when we use x = 0
Then the y-intercept is:
P(0) = $8*0 - $150 = -$150
Also the graph of the equation can be seen below, where you need to remember that x can be any value in [0, 200] and only can be an integer.
So you only need to graph the line between x = 0 and x = 200.
