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 expressed in the graph below. what is the meaning of the x - value when y = 80?

Explanation:

In a graph, the \(x\)-axis and \(y\)-axis have specific meanings. Here, the \(x\)-axis represents "Chirps Per Minute" and the \(y\)-axis represents "Temperature (Degrees Fahrenheit)". When we are looking for the \(x\)-value when \(y = 80\), we are using the relationship shown in the graph. The graph depicts a linear relationship between the two variables. By finding the point on the line where the \(y\)-coordinate is \(80\) and then determining the corresponding \(x\)-coordinate, we are essentially answering the question: "At a temperature of \(80\) degrees Fahrenheit, how many times does the cricket chirp per minute?"

Answer:

The \(x\)-value when \(y = 80\) represents the number of times the cricket chirps per minute when the temperature is \(80\) degrees Fahrenheit.
