Bellringer …Monday

This lesson focuses on solving for x and determining values of J from the equation presented in Bellringer. Graded quizzes will be posted in IC soon, and students have until Thursday to make up any missed assessments. Key topics include writing equations for parallel and perpendicular lines, using slopes, and understanding midpoint and distance formulas in coordinate geometry. Practice problems can be accessed through interactmath.com, using the Prentice Hall Geometry 2011 text. Be ready for the upcoming Unit 1 and 2 Test.

Presentation Transcript

  1. Bellringer…Monday J 12x + 3 4x + 35 • Find the value of x. Then find the value of < J.

  2. Quizzes. • They are graded and will be in IC soon—I have no internet at home.  • Most people did a WONDERFUL job. At least a couple perfect scores in every class. I am impressed with you all! • If you missed it, you have until Thursday to get it made up. • FYI: The material will show up again on a Unit 1 & 2 Test.

  3. Unit 2: Coordinate Geometry Slope—writing equations for lines Midpoint—find it or use to find an endpoint Distance—how far? Use coordinate geometry to solve problems about figures (segments, triangles, quadrilaterals)

  4. Parallel • Looks like: • Means: • Slope:

  5. Write an equation: Parallel to y=3x + 5 and through the point (-4, 2). Plug it in, plug it in!

  6. Perpendicular • Looks like: • Means: • Slope:

  7. Write an equation: Perpendicular to y=3x + 5 and through the point (-6, -1). Plug it in, plug it in!

  8. Practice: • Go to interactmath.com • Select: Prentice Hall, Geometry 2011 • Click “enter” • To save, take a print screen. Hold “Fn” and “F11” buttons at the same time. Then paste into a word document, saving as HW1.
