Answer:

$y=5x+15$

Step-by-step explanation:

Since this situation is a linear relationship between the number of movies and the total cost, we need to determine the slope of the line given our two ordered pairs $(x_1,y_1)\rightarrow(5,40)$ and $(x_2,y_2)\rightarrow(12,75)$ :

$m=\frac{y_2-y_1}{x_2-x_1}\\ \\m=\frac{75-40}{12-5}\\ \\m=\frac{35}{7}\\ \\m=5$

Thus, our equation so far is $y=5x+b$ . Next, we need to find our y-intercept, $b$ , which represents our flat fee. We do so by using one of our original given ordered pairs:
