  1. Forms of Linear Functions Day 1: Slope-Intercept Form

  2. Tuesday 10/19

  3. WARM-UP 10/19 • What is the slope of the line that passes through the points (−6,8) and (-16, 33) ? Write your answer in simplest form. _____ 33-8 -16 + 6 25 -10 2. What is the slope in the graph below? Remember Rise over Run! Correlation: ______________ Rise : ___________________ Run: ___________________ Slope: m = ________________

  4. WARM-UP 10/19 What is the slope of the line that passes through the points (−6,8) and (-16, 33) ? = 25 = - 5 -10 2

  5. WARM-UP 10/19 What is the slope in the graph below? Correlation: Positive Rise : 1 Run: 3 Slope: m = 1/3

  6. Wednesday Early Dismissal Schedule 10/20

  7. Name: _______________________ WARM-UP Directions: Identify the slope for the following problems. 3 - (-1) -4 - (-2) 2). = (-4,3) 1). (4,3) 3 - (-1) 4 - 1 = 4 3 (-2,-1) (1, -1) m = ______-4/2__________ m = _______4/3__________ 3) (−4, 7), (−6, −4) 4) (20, 8), (9, 16)

  8. 1). 2). m = -4/2 = -2m = 4/3

  9. 3) (−4, 7), (−6, −4) 4) (20, 8), (9, 16) 16 - 8 8___-8 9 - 20 9 + (-20) 11 −4 - 7-4 + (-7)-1111 -6 - (-4) -6 + 4 -2 2

  10. To graph your equation... • Begin by plotting your y-intercept (b value in your equation) • Use the slope to move to the next point (rise/run) • Repeat to make at least 1 additional point • Draw a straight line through the three points

  16. m = 2) Write the equation. *Use the slope and the given y-intercept to write the equation of the line in slope-intercept form. b = 1 y =

  17. m = 2 2) Write the equation. *Use the slope and the given y-intercept to write the equation of the line in slope-intercept form. b = 1 y =

  18. m = 2 2) Write the equation. *Use the slope and the given y-intercept to write the equation of the line in slope-intercept form. b = 1 y = 2x + 1

  19. y=mx+b m = slope (rise/run) b = y-intercept (given in this example m = m = b = 3 b = -5 y = y =

  20. 2 - 4 2-(-2) -2 4 m = -1/2 m = -1 2 b = 3 b = -5 y = y =

  21. m = -1/2 b = 3 y = -1/2x + 3 y = mx + b

  22. To Do: • Sharpen pencils • Copy HW in your Agenda • Complete the Warm- Up *If you were absent please check the Make-Up work bin.* 10/21 AGENDA IMPORTANT! • There will be a Mini-Quiz on Friday Covering Slope • DeltaMath HW#6- Slope Intercept Form due by 10/24 • CHECK WARM-UP- do 1,2 &3 ONLY! • REVIEW FOR QUIZ • DELTAMATH TIME! Outcome: I can graph the slope and y-intercept of a liney = mx + b

  23. Time to practice what we have learned! • Go to Brightspace • Mathematics • Content
