Question

theres a roughly linear relationship between the number of times a species of cricket will chirp in one minute and the temperature outside, as represented in the graph below. what is the meaning of the x - value when y = 75?
answer
the expected temperature in degrees fahrenheit if the cricket has chirped 75 times per minute.
the expected temperature in degrees fahrenheit if the cricket has chirped 108.6 times per minute.
the number of times the cricket could be expected to chirp in one minute if its 108.6°f.
the number of times the cricket could be expected to chirp in one minute if its 75°f.

Explanation:

Step1: Identify the axes

The \(x -\)axis represents "Chirps Per Minute" and the \(y -\)axis represents "Temperature (degrees Fahrenheit)".

Step2: Analyze the meaning of \(x\) when \(y = 75\)

When we are looking for the \(x -\)value when \(y=75\), since \(y\) is the temperature and \(x\) is the number of chirps. We are essentially finding the number of chirps (\(x\)) corresponding to a temperature (\(y = 75\)).

Answer:

The number of times the cricket could be expected to chirp in one minute if it's \(75^{\circ}F\).
