1 Graphing Lines Section 4.6

2 x- and y- intercepts x – intercept: (2, 0) y – intercept: (0, -3)

3 Slope (2, 0) (0, -3) 2 3

4 4. What is the slope of the line y = 223x – 10 ?
What is the y-intercept of the line y = 223x – 10 ? What is the slope of the line y = x + 15? What is the y-intercept of the line y = x + 15? What is the slope of the line y = mx + b? What is the y-intercept of the line y = mx + b?

5 Graphing Lines slope and y-intercept

6 y = 2x + 1 y = 2x + 1 Run 1 y-intercept Rise b = (0, 1) 2 slope m = 2

7 y = -3x + 2 y = -3x + 2 1 -3 y-intercept b = (0, 2) slope m = -3 Run
Rise b = (0, 2) -3 slope m = -3

8 Run 3 Rise y-intercept: 2 b = (0, -1) slope:

9 Run 2 Rise -1 y-intercept b = (0, 3) slope:

10 Run 3 Rise -1 y-intercept b = (0, 1) slope:
