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.

14. Given (1, 3) and (4, y), what would y have to be to have a slope of -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 .
