1. Warm ups Find the x and y intercepts: 3x -9y = 18
Write in Point-Slope Form:
(5,-3) m = -2 (3,4) (-1,8)
Write in Standard Form:
(2,3) (0,3) (4, -5) m = -3

3. 6-4 Slope-Intercept Form
Objective: To write an equation in slope-intercept form.

4. y = mx + b Slope-Intercept Form m = slope
Does anyone know what it is?...
y = mx + b
m = slope
b = y-intercept (this is on y axis)

5. Given slope and y-intercept
Example 1: Write an equation in slope-intercept form
Given: m = 4 b = -2
y = 4x – 2
Example 2: Write an equation in slope-intercept form
Given:

6. Write in Slope-Intercept
5x – 4y = 20

7. Example 5 Write an equation in slope-intercept form given: (2,1) (4,0)
(2,1) (4,0)
Steps:
Find slope
Plug into point-slope
Convert to slope-intercept
x1 y x2 y2

8. Example 6 Write an equation in slope-intercept form given: (0,6) (4,0)
(0,6) (4,0)
x1 y x2 y2

9. Given a graph Example 7: write an equation in slope-intercept form
b = 2
m = -2/3 -2 3

10. Given a graph TOO: write an equation in slope-intercept form b = -4
y = x – 4 1 1

11. TOO – students can present.
m = 5, b = -3
y – 2 = 4(x + 7)
(-2,-3) (-1,2)
Answers:
y = 5x – 3
y = 4x + 30
y = 5x + 7
