15 questions

ME = 85% - 100%
AP = 60% - 84%
DM = 0% - 59%

For the following problems:
(1) Draw a line of best fit
(2) Write a prediction function (equation in y=mx+b form)
(3) Use your prediction function to make predictions!

Muzgan just opened up a new hair salon in Skokie on Oakton Street.  The scatterplot below shows the amount of money Muzgan makes in tips based on how many clients she has in a day. 

Draw a line of best fit on the scatterplot.

Use the straight line tool!

Hint - Make sure the y-intercept is 0!

The following scatterplot shows the final quarter grades in Mrs. Gormley's science class for students compared to the number of times they were absent.  

Blake is interested in the association between the time spent on studying for a test and the score that is earned.  He surveys 30 people about the time they spent studying for a test and the score that they earned on the test.  His data is in the scatter plot below.

Draw a line of best fit on the scatterplot.Use the straight line tool!Hint - Your y-intercept should be 90 and your x-intercept (the point on the x-axis) should be 24... Plot the 2 intercepts on each axis and create your line of best fit!

Find the slope (m) and y-intercept (b) and write the prediction function in y=mx+b form!If you're having a hard time finding the slope... use the 2 points in the hint to CALCULATE IT: (0,90) & (24,0)Slope = (y-y)/(x-x)SHOW WORK FOR FINDING SLOPE!
