Slope and y- intercept By Ms. Morgan

2
Do now Find the slope of these two points: (-2, -2) and (4, 1) (-2, -2) and (4, 1) Find the slope of these two points

3
Slope and Y -Intercept Video http://www.phschool.com/atschool/acade my123/html/bbapplet_wl-problem- 431001.html http://www.phschool.com/atschool/acade my123/html/bbapplet_wl-problem- 431001.html http://www.phschool.com/atschool/acade my123/html/bbapplet_wl-problem- 431001.html

4
Example What is the slope and y-intercept? 1.Y = 4x + 6 2.Y = 1/3x – 7 –Build the equation with the following slope and y-intercept: Slope= 9 y-intercept = -3 Slope= 1/6 y-intercept = 5

5
Writing Equations from graphs Video http://www.phschool.com/atschool/acade my123/html/bbapplet_wl-problem- 431002.html http://www.phschool.com/atschool/acade my123/html/bbapplet_wl-problem- 431002.html http://www.phschool.com/atschool/acade my123/html/bbapplet_wl-problem- 431002.html

6
Practice Write the equation for the following graph First find the slope Then find the y- intercept Finally place slope and y-intercept in the form Y= mx + b

7
Example 2 Write the equation for the following graph First find the slope Then find the y- intercept Finally place slope and y-intercept in the form: Y= mx + b
