A film crew follows employees in an office around for a day. The crew has already captured several hours worth of footage of the employees at work. The crew spends more time recording one-on-one interviews with each of the employees getting their take on the day. The equation m=15p+180 represents the length of minutes, m, of footage the crew has captured after they interview p employees. The coordinate (8, 300) corresponds with the film crew once they've finished filming for the day.

Match each number to the answer that BEST describes it.

• How many minutes of footage the crew filmed before interviews

• 300

• How many employees were interviewed

• 15

• How many minutes of footage the crew filmed once all interviews were conducted

• 180

• How many minutes each employee is interviewed for

• 8

Hint: You will need Desmos with this question. Remember the magic equation y1~mx1+b

Mrs. Kelly's class started a new book. After skipping a handful of pretext pages in the beginning, the class reads the same number of pages per day. The class can use the equation p=20d+3 to determine the page number, p, they are on in the book based on how many days, d, they have been reading the book. The coordinate (18, 363) is the solution to the equation that corresponds with the day the class finished the book. Match each of the following numbers to the description that BEST matches it.

• The number of pages the class skipped.

• 20

• The number of pages the class read each day.

• 363

• How many days it took the class to finish the book.

• 3

• The page-length of the book.

• 18
