Medhavi suspects that there is a relationship between the number of text messages high school students send and their academic achievement. To explore this, she asks a random sample of 52 students at her school how many text messages they sent yesterday and what their grade point average (GPA) was during the most recent marking period. Her data are summarized in the scatter plot below. The line of best fit is also shown.
The equation of the line of best fit is y = 3.8-0.005x. Interpret the quantities β0.005 and 3.8 in the context of this data (consider slope-intercept form y=mx+b).
Part A) -0.005 is the and represents:
Part B) 3.8 is the and represents:

David estimated he had about 20 fish in his pond. a year later, there were about 1.5 times as many fish. the year after that, the number of fish increased by a factor of 1.5 again. the number of fish is modeled by f(x)=20(1.5)^x. create a question you could ask that could be answered only by graphing or using a logarithm.
