1. Lesson 4 Algebra II Advanced Functions

2. Slope a)What is the slope of a horizontal line? 0 b)What is the slope of a vertical line? undefined c)What are the slopes of the lines on the board? 4/3, -2

3. d)What is the slope of the line through (3,1) and (0,7)? -2 e)What is the slope of the line through (2,-3) and (-10,-7) 1/3

4. f)What is the slope of the line through (2,5) and (15,5)? 0 g)What is the slope of the line through (3, 4) and (3,-9)? undefined

5. h)What is the slope of the line y = 9 – 4x? -4 i)What is the slope of the line y = x? 1 j)What is the slope of the line 3x + y = 15? -3

6. k)What is the slope of the line 6x – 2y = 8? 3 l)What is the slope of pool slide that is 75 feet tall and 100 feet long? 3/4

7. Graphing a) y = 4x – 7 b) y = -1/2x + 5 c) y = 3x d) y = 4 – x e) 4x + 2y = 12

8. f) 5x – 2y = 12 f) y – 7 = -3x g) x + 1 = 6 h) 2x + 6 = 3y

9. Writing Equations a)For the lines on the board. b)For the line with a slope of 5 and a y- intercept of -2. y = 5x - 2 c)For a line through (3,-2) with a slope of -4. y = -4x + 10 d)For the line through (2,5) and (6,7). y = 1/2x + 4
