Presentation Transcript

  1. Do Now • Find the slope of the line passing through through the points (-3, 6) and (-9, 7) • Find the slope for the picture below and describe what it represents. • Solve: • -3x – 8 < 13 4.

  2. Today – Til Break  • Today/Tomorrow • Coordinate Plane and Graphing with Slope • Thursday/Friday • Coordinate Plane and Graphing with Slope • December 10th and 11th • I will be out • Tuesday: Law School Final • Wednesday: Presenting at a conference in Michigan • December 12th and 13th • Concept Quiz on Coordinate Plane and Graphing with Slope • December 17th and 18th • MAP Testing!!!! • December 19th and 20th • Re-Takes/Make-Ups/Edgenuity Help

  3. Review Concept Quiz

  4. Coordinate Plane Refresher • X is ALWAYS First • Y is ALWAYS Second • Start at the Origin (0,0) (-4, -1) (0, 3) (-2, 1) (2, 4) (-3, 0)

  5. Coordinate Plane/Graphing Practice Locating the Aliens

  6. Graphing with Slope • Write out the Rise and Run for the Slope • Plot the Point • Use the rise then the run to get the next point • Connect!

  7. Graphing with Slope • Key Terms • Parallel Lines • Lines that have the same slope – never cross! • Perpendicular Lines • Lines that cross at a right angle • Intersecting Lines • Lines that cross each other but are NOT perpendicular

  8. Slope: -1 Passing through (4, 2)

  9. Passing through (0, -2) and (1, 3)

  10. Do Now Find the Slope of the line crossing through the following points (-4, 5), (-2, -5) (3, -4), (3, -2) (-1, 0), (8, 1)

  11. Slope: -3 Passing through (-4, 2)

  12. Slope: ⅙ Passing through (0, -5)

  13. Slope: 0 Passing through (-3, 5)

  14. Slope: Undefined Passing Through: (5, -2)

  15. You Try • Slope: -⅗ Passing through (4, 0) • Slope: 0 Passing through (2, 1) • Undefined slope, passing through (-1, 4) • Passing through (-4, 6) and (1, 8) and find the slope • Passing through (-3, 4) and (-7, 2) and find the slope

  16. Do Now 1. Draw the graph of a line with a slope of -¾ passing through the point (0, -2). List the rise and the run. • Draw a line with a slope of 3 passing through the point (-1, -5). List the rise and the run. • Draw the following two lines: First: Slope of -2 passing through the point (0, -1) Second: Slope of -2 passing through the point (-3, 6) What type of lines are these??

  17. Review Concept Quiz • We are going to review the Concept Quiz from last Thursday • You will then have three options • Retake a new version • Sign out a computer silently and work on your coursework • Head upstairs to the LC and work your coursework
