Question 1151187: The outside temperature can be estimated based on how fast crickets chirp.
At 104 chirps per minute, the temperature is
63
°F.
At 176 chirps per minute, the temperature is
81
°F.
Using this information, you can make a formula that relates chirp rate to temperature. Assume the relationship is linear, that is the points form a straight line when plotted on a graph.
What is the temperature if you hear
148
chirps per minute?
What is the temperature if you hear
84
chirps per minute?

let the number of chirps be and the number of degrees
At chirps per minute, the temperature is °F. we have
and
that is a point ( , ) on a line
At chirps per minute, the temperature is °F.
that is a point ( , ) on a line
the equation of a line is:
where is a slope and is y-intercept
using given points find slope :

.....simplify, divide both numerator and denominator by

.......now use one point to find

your equation is:

What is the temperature if you hear chirps per minute?
given:

=> the temperature is °F

What is the temperature if you hear chirps per minute?
given:

=> the temperature is °F
