This is clearly a linear relationship. If Alex rented the movie for 0 days, he'd owe nothing. If he paid $6 for a 3-day rental, the slope of this line would be m = rise / run = $6/(3 days) = $2/day, which is positive.
Then the equation for this graph is C(x) = ($2/day)x, where x is the number of days for which the movie is rented.
Using this formula, we find three particular points on the graph:
(1, $2), (2, $4), (3, ($6)

7.125
and 5.1
Step-by-step explanation:
Hi so have you heard of KFC? It stands for keep flip change. You use it when adding or subtracting or when you're dividing fractions. So you keep the first part of the problem the same; you flip the sign of the second part, and change the sign of the third part. So -23.9- -9.3 becomes -23.9 + +9.3. So take away 9.3 from 23.9 and get 14.6. Whenever you add a positive to a negative like we do here, the answer will become a smaller negative number if the positive number is "smaller" than the negative number.
