Chirps and Temperature Relationships

The video tutorial explains how the number of chirps per minute by tree crickets is linearly dependent on temperature in Fahrenheit. It starts by establishing the relationship using ordered pairs and derives a linear equation in slope-intercept form. The tutorial then calculates the slope and intercept, and applies the equation to determine the number of chirps at a given temperature, specifically at 60 degrees Fahrenheit.

• Linear

• Logarithmic

• Exponential

• Quadratic
