(3 points)
A. What is the equation for the Linear Regression Line?
B. There is a _ correlation between the test marks and the homework marks.
C. The slope of the line of best fit can be used to make a probabilistic interpretation that states _
Word bank:
positive
y = 0.72 - 38
The test mark increases 1 pt for every 1 pt on the homework mark.
The test mark decreases 0.7 pts for every 1 pt on the homework mark.
y = 0.89x = 36.7
y=-37x+1
The homework mark increases 37 pts for every 1 pt. on the test mark.
y = -x + 37
The homework mark increases 0.89 points for every 1 pt. on the test mark.

Negative
A. The equation for the Linear Regression Line is y = 0.89x + 36.7.
B. There is a positive correlation between the test marks and the homework marks.
C. The slope of the line of best fit can be used to make a probabilistic interpretation that states the homework mark increases 0.89 points for every 1 pt. on the test mark.
