Pre-Algebra: Day 46Ms. Ubik Warm-up: Compete the worksheet you picked up off the table. Write an equation in slope-intercept form for each situation. If you don’t remember what slope-intercept form is LOOK IT UP (I know I had you write it down!)
TARGETS: • Complete Barbie Bungee Lab • Use lines to predict outcomes
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.

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?
