8.EE.6 Day 2

Day 2 – Bringing y=mx to y=mx+b

*Finish the multiple points on a single line. Similar triangles?

Focus Q – What does a linear equation look like when it is not proportional?

This lesson is all about setting up the need for a y-intercept of “b” in the equation.

  • Where would the equation y=50x start from?
  • When would an equation not start from there? What would that look like?
  • Tech Weigh In Rich Task
    • Compare direct variation to y=mx+b back to back
    • Allow for plenty of time for students to attempt to find the macbook weight.
      • Emphasize that this is the starting weight.
      • It would helpful to find the weight of 1 iPad.
