A researcher studied the relationship between the number of times a certain species of cricket will chirp in one minute and the temperature outside. Her data is expressed in the scatter plot and line of best fit below. What does the point left bracket, 134, comma, 75, point, 6, right bracket(134,75.6) represent?
Question
A researcher studied the relationship between the number of times a certain species of cricket will chirp in one minute and the temperature outside. Her data is expressed in the scatter plot and line of best fit below. What does the point left bracket, 134, comma, 75, point, 6, right bracket(134,75.6) represent?
Solution
The point (134, 75.6) on the scatter plot represents an observation or data point that the researcher recorded. Specifically, it means that when the outside temperature was 75.6 degrees (although the units aren't specified, they're typically Fahrenheit or Celsius in such studies), the crickets of the certain species chirped 134 times in one minute.

Adrian records the number of chirps per minute ( x ) that crickets make at different temperatures ( y ).He determines that the association is linear and that the line of best fit is 𝑦=15𝑥+50y= 51 x+50.What is the interpretation of the slope and y-intercept of this equation?Click here for long descriptionA.The slope predicts a temperature increase of about 1° for every increase of 50 chirps per minute. The y-intercept shows that when the crickets are not chirping (x = 0), the temperature is 1551 °.B.The slope predicts a temperature increase of about 1551 ° for every increase of 1 chirp per minute. The y-intercept shows that when the crickets are not chirping (x = 0), the temperature is 50°.C.The slope predicts a temperature increase of about 50° for every increase of 1 chirp per minute. The y-intercept shows that when the crickets are not chirping (x = 0), the temperature is 0°.D.The chirping increases as the temperature goes down.
