Welcome to Math Class: Understanding Slope and Y-Intercept

In today's math class, we will dive into the concepts of slope and y-intercept in linear equations. You will learn to identify the slope (m) and y-intercept (b) from equations in slope-intercept form, y = mx + b. We will perform graphing exercises, including inequalities and systems of equations. Participation is key! Stay engaged by sending your answers in the chat box and using whiteboard tools as directed. Let's check understanding with a survey and ensure everyone is ready to graph on a coordinate plane!

Presentation Transcript

  1. Bell Ringer Review Welcome to Math Class Send your answers to me in the chat box. Identify the slope and y-intercept of the equation. y=- Raise your hand when you have typed your answer in the chat box • Be present at your computer during ALL of class. • Have eyes on me and BBC. • Ears listening and ready to follow instructions. • Keep chat on topic. • Use whiteboard tools and programs as directed.

  2. Way to go!!!!

  3. Objectives Content: I can graph linear equations and inequalities on a coordinate plane Language: I can use the appropriate vocabulary to explain how to graph linear equations and inequalities on a coordinate plane using a graphic organizer

  4. Review In the slope intercept form y=mx+b, what does m stand for? • x-intercept • Y-intercept • Slope • A line

  5. Review In the slope intercept form y=mx+b, what does b stand for? • x-intercept • Y-intercept • Slope • A line

  6. Review y=- x+8 What is the slope? What is the y-intercept?

  7. Review y=4x-6 What is the slope? What is the y-intercept?

  8. Yes!!!!!

  9. Check Understanding Give me an a-e. • A I don’t understand at all. • B I understand a little, but not very well • C I understand pretty well, but still make lots of mistakes • D I understand it how to do it, but couldn’t explain or help some one very well • E I completely understand and could help a classmate.

  10. Review y=x+5

  11. I can graph lines on a coordinate plane Slope-Intercept Form

  12. I can graph lines on a coordinate plane

  13. YOU DID IT!!!!

  14. Check Understanding Give me an a-e. • A I don’t understand at all. • B I understand a little, but not very well • C I understand pretty well, but still make lots of mistakes • D I understand it how to do it, but couldn’t explain or help some one very well • E I completely understand and could help a classmate.

  15. Graphing Inequalities The first difference between graphing an equation and graphing an inequality is that we either graph a _____ for or a ------- for > < Then we get to shade!

  16. Graph a solid line for • >, < Graph a dotted line for • >, <

  17. I can graph an inequality on a coordinate plane

  18. I can graph an inequality on a coordinate plane

  19. I can graph an inequality on a coordinate plane

  20. Wahoo!!!!!

  21. Check Understanding Give me an a-e. • A I don’t understand at all. • B I understand a little, but not very well • C I understand pretty well, but still make lots of mistakes • D I understand it how to do it, but couldn’t explain or help some one very well • E I completely understand and could help a classmate.

  22. Systems of Equations Where 2 lines cross. This is called the solution or solution point.

  23. Systems of Equations

  24. Systems of Equations

  25. Yes!!!!!

  26. Solve the system of equations by graphing

  27. Solve the system of equations by graphing x - 3

  28. Wahoo!!!!!

  29. Check Understanding Give me an a-e. • A I don’t understand at all. • B I understand a little, but not very well • C I understand pretty well, but still make lots of mistakes • D I understand it how to do it, but couldn’t explain or help some one very well • E I completely understand and could help a classmate.
