#### Storyboard Text

• Okay, time to make the next chapter in my Wilderness Trailbook!
• But what should it be about...? Oh, I know! I'll write about how the temperature effects the number of times a cricket chirps in a minute!
• Seriously?
• Let's see... to prove I'm right I'll have to show that the rate at which crickets chirp is a linear function of temperature by using the equation y=mx+b
• Alright, it's 59 degrees right now and the cricket next to me has chirped 76 times, this means that at 59 degrees, crickets chirp 76 times per minute...
• And now it's 65 degrees and the cricket has chirped 100 times in the past minute. That means that at 65 degrees, crickets chirp 100 times per minute
• So after some quick math, I can know that the equation for my problem is y=4x-160! 4 being the slope of my function and -160 being the y-intercept!
• So that means that every time the temperature raises by 1 degree, the number of times the cricket chirps increases by 4!
• Now people know how many times a cricket chirps in a minute! Such valuable information! Time to work on the next chapter!
