Whoever this very adventurous kid is…
You did an experiment this weekend while watching the
Bears Game. You noticed that when Cutler threw 3 passes, he had 1 reception. When he
threw 5 passes, he had 3 receptions. When he threw 9 passes, he had 5 receptions,
and at 18 passes, 11 receptions
Lets graph this data and write a line to
satisfy the equation.x y

Now lets write an equation of this
line…To write the equation of a line in slope intercept form,
you need two things:1.) The slope of the line
2.) The y-intercept of the line
Predicting
• We can use this equation to predict statistics about Cutler.
• For example, use the equation to predict how many receptions there would be if Cutler threw 6 passes.
• 11 passes?• 39 passes?
Predicting
• We can also predict the y-values…• For example, use the equation to predict
how many passes Cutler would have to throw for 10 complete receptions.
• 15 receptions?• 22 receptions?
