Q:

Biologists have found that the number of chirps some crickets make per minute is related to temperature. the relationship is very close to being linear. When crickets chirp 124 times a minute, it is about 68 degrees Fahrenheit. When they chirp 172 times a minute, it is about 80 degrees Fahrenheit.Identify the variablesx= ___________y= ___________y-intercept= __________slope= _______Create an equation in y=mx+b formHow warm is it when the crickets are chirping 150 times a minute? Please help, I have to turn this in tomorrow 45 POINTS​

A:
Answer:   points (x, y) = {(124, 68), (172, 80)}   y = 1/4x +37Step-by-step explanation:For the variable definitions given, the problem statement gives you the points ...   (chirps, temperature) = (x, y) = (124, 68)  or  (172, 80)__You are asked to find a linear equation that relates x and y.The slope can be found using the slope formula:   m = (y2 -y1)/(x2 -x1)   m = (80 -68)/(172 -124) = 12/48 = 1/4The y-intercept can be found from ...   b = y -mx   b = 68 -(1/4)(124) = 37Then the equation that models the relationship can be written ...   y = 1/4x +37
