In this Pre-Algebra warm-up activity, students will complete a worksheet and master writing equations in slope-intercept form. We will analyze data from a recent Bears game, observing the relationship between the number of passes thrown by Cutler and his receptions. Students will graph the data points and derive an equation to predict future outcomes. By applying the concepts of slope and y-intercept, learners will enhance their ability to predict statistics based on linear equations. This hands-on approach connects math to real-life sports scenarios.

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?
