Draw a line of best fit on the scatterplot.
Use the straight line tool!
Hint - Make sure the y-intercept is 0!
Pick 2 points form your Line of Best Fit and find the slope (m) and y-intercept (b) and write the prediction function in y=mx+b form!

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)

Use your prediction function to PREDICT the score for a student who studied for 160 minutes.
SHOW YOUR WORK!
Using the prediction function, we got an answer that PREDICTS what someone's test score would be after studying for 160 minutes...
According to the scatterplot, what were the ACTUAL scores of the 2 students who studied for 160 minutes?
Would you say your prediction function works well? Explain
