CCSS.Math.Content.8.EE.B.6 Use Similar...

CCSS.Math.Content.8.EE.B.6 - Use similar triangles to explain why the slope m is the same between any two distinct points on a non-vertical line in the coordinate plane; derive the equation y = mx for a line through the origin and the equation y = mx + b for a line intercepting the vertical axis at b.

  1. Finding the X Intercept and Y Intercept to Graph Standard Form Equations - Five practice problems to practice using what was learned in the lesson above, followed by an answer key
  2. Fun and Sun Rent-a-Car - Students use tables, graphs, linear functions to solve a real-world problem
  3. Graphing linear equations - Practice from Math.com
  4. Practice Converting Linear Equations into Slope-Intercept Form - This show provides several opportunities for student practice [25 slides]
  5. Rate of Change Practice Problems - Nine practice problems (including a graph to interpret) followed by an answer key
  6. Rate of Change: Connecting Slope to Real Life - A lesson on using slope to find the rate of change accompanied by graphs and explanations
  7. Representations of Linear Functions: Cab fares - The charge for a cab ride is determined by the length of travel. Some companies also charge a basic, fixed amount. At this site you will find descriptions of fares of three competing cab companies and you are asked to suggest a new fare.
  8. Slope Intercept Jeopardy - This show is in Jeopardy format; with five categories each with five questions - good for a while class review
  9. Straight Lines and Slopes - Explanation from Regents Prep assessment preparation site [from the Internet archive, the Wayback Machine.]
  10. Using the X and Y Intercept to Graph Linear Equations - This follow up to the lesson on slope and rate of change deals with linear equations written in standard form rather than slope intercept form
  11. Word Problems with Katie - Two levels are available: addition and subtraction in level 1, and multiplication and division in level 2 - questions start out easy and get a little harder as you go
