8.EE.6 Day 3

Day 3 – Focusing on the Y-Intercept

Focus Q – What does the “b” in the equation y=mx+b represent?

  • Begin by going over the equation comparison paragraph
  • Attempt to derive what the b is referencing. Give another example to showcase what b is referencing:
    • Ex: I need to rent a car. It costs $25 to reserve a car and then $50 per day. What equation describes this relationship?
    • also need examples of negative y-intercept
  • students should be able to identify where the y-intercept is on a table, equation and graph

So, what do you think ?
