Learning  Target:  •  I  can  use  the  graph  to  determine  whether  2  ra,os  form  a  propor,on.  •  I  can  interpret  graphs  of  propor,onal  rela,onships.    Agenda:  •  Do  Now  •  Hw  Check  •  Ac,vity  1:  Find  the  speeds  •  Ac,vity  2:  Which  animal  is  faster?    Which  graph  is  steeper?  •  Slope  –  How  to  find  it  •  Example  1:  Find  slope  from  the  graph  of  a  line  •  Example  2:  Interpret  slope  given  a  graph  •  Summarize    Homework:  5.5  Exercises,  pp.  196  –  197,  #  4-­‐12  even,  13-­‐16  

Today:  5.5  Slope

What  does  a  unit  rate  tell  us  about  speed?  If  these  relaOonships  were  graphed,  which  animal’s  graph  of  Ome  compared  to  distance  would  be  the  steepest?    How  does  speed  connect  to  slope?    How  does  this  compare  to  our  acOvity  yesterday  when  we  found  rates  of  walking?
