Lesson 5-3: Construct Linear Functions

Each week, Sam works the same number of hours. Her first week included an orientation. The total number of hrs that she worked after the 2nd, 3rd, and 4th weeks was 20 hours, 28 hours, and 36 hours respectively.

Part A: Find the rate of change

Each week, Sam works the same number of hours. Her first week included an orientation. The total number of hrs that she worked after the 2nd, 3rd, and 4th weeks was 20 hours, 28 hours, and 36 hours respectively.

Part B: Find the time spent on orientation (initial value):

Angelica started a book and now plans to read 15 pages of it each day. In 10 days, she reads 200 pages. Assume the relationship is linear.

Part A: Find the Rate of Change

Angelica reads 15 pages of a book each day. In 10 days, she reads 200 pages. Assume the relationship is linear.

Part B: Find the initial value, the number of pages she had already read:

Maria has started collecting baseball cards. She collects 20 cards each week. After 9 weeks, Maria has 250 cards. Assume the relationship is linear.

Part A: Find the Rate of Change

Maria has started collecting baseball cards. She collects 20 cards each week. After 9 weeks, Maria has 250 cards. Assume the relationship is linear.

Part B: Find the initial value, the number of cards already collected
