Activities
- A line of best fit drawn for a scatterplot representing the number of chapters (x) in a book and the total number of pages (y) has an equation of y = 12x. What is the slope of this line and what does it mean?
- A line of best fit drawn for a scatterplot representing the number of chapters (x) in a book and the total number of pages (y) has an equation of y = 12x. What is the y-intercept of this line and what does it mean?
- You have a savings account into which you plan to deposit the same amount of money each month. The total amount in the account, y, after x months is represented by the equation y = 125x + 1200. What is the amount you are depositing monthly? Why? How much will be in your account after a year? Show your work.
- Use the given equation y = -200x + 2400 to come up with a situation it could represent. Explain.
Answer Key/Rubric
- The slope is
which means an average of 12 pages per chapter.
- The y-intercept is (0, 0), which means on average a book with 0 chapters has 0 pages.
- You are depositing $125 each month, which is the slope of the equation. You will have $2700 in your account after a year (12 months).
Student work may include, but is not limited to:
- Answers will vary. Student examples should include a slope of -200 and a starting point of 2400.
