  1. Day 9 Assignment

  2. Write an equation for the line: • Y = x+ 2 • 2x + 2y = -1 • Y = 1/2x – 2 • 3x – 3y = 6 1.

  3. What would be the missing piece of information given the following information: Find the equation of the line that passes through the points (2, 6) and (4, 10). y = 2x + ? a. 4 b. 2 c. 7 d. 5 2.

  4. Complete this sentence with the correct choice: y = 4 is a horizontal line with ________. a. undefined slope. b. a slope of 4. c. a slope of 0. d. None of the above will make a true statement. 3.

  5. 4.

  6. Which of the following is the equation of a line with a slope of 0 and passing through the point (4,6)? • X = 4 • X = -4 • Y = 6 • Y = -6 5.

  7. The rate of change of a horizontal line is: • Positive • Undefined • Zero • negative 6.

  8. What is the rate of change of the following graph? • 3 • 1/3 • -1/3 • -3 7.

  10. The graph for a technician that charges a $10 flat fee plus an hourlyrate is shown below. What is the hourly rate charged? • $12 an hour • $9 an hour • $5 an hour • $20 an hour Cost Hours 9.

  11. The rate of change is the same thing as the _____________. 10.

  12. 11.

  13. 12.

  14. Given (1, 3) and (4, y), what would y have to be to have a slope of -3? • -3 • -6 • -9 • 4 Since I’m not here today, here’s a hint. Plug answer choices in for the missing y, do stat edit, and see which ones gives you a slope of -3 . 13.
