Question 998605: Entomologists have discovered that a linear relationship exists between the number of chirps of crickets of a certain species and the air temperature. When the temperature is 70F, the crickets chirp at the rate of 120 chirps/min, and when the temperature is 80F, they chirp at the rate of 160 chirps/min. Find N as a function of T and use this formula to determine the rate at which the crickets chirp when the temperature is 109F.

You can put this solution on YOUR website! Would this be easier or more familiar a problem to solve?
Find the equation of the line in slope-intercept form which contains the points (70,120) and (80,160). Use this equation to find y for when x=109.

(x,y) would correspond to (T, N).
