Press ENTER to get the line of best fit. (If you press Y= , you will notice that the regression equation you just calculated is in Y1.) Notice that the values for a and b are given. The value of r is the correlation coefficient. The closer the value is to 1, the closer the plotted points are to the line of best fit.

L1 represents x. We got L3 by multiplying L1 and L2. So if we multiply our equation in Y1 times x, we should get a good fit for this graph. The next two screen shots display this. Just as we used LinReg to find the line of best fit for Q and P, as given on the first page, we can use Stat Calc 5:QuadReg to arrive at the same equation.

Using the statistical functions of your TI- 84 Plus calculator, determine a line of good fit for each of the following categories. Score on Test 1 (L1) versus hours watching television (L2): Score on test 1 (L1) versus score on test 2 (L2):
Activity overview:
An alternative to using Manual-Fit to draw the line of best fit, students can use the Transformation Graphing App. They need to enter AX + B next to Y1 and then set A=1, B=1 and step=0.1. Extension 1 – Calculator-generated lines of best fit This activity can be extended (or continued the next day) to find calculator generated lines of best ...

(TI-84 Plus family) — 6194. What’s My Model? (TI-Nspire technology) — 8518 One goal of this exploration is to see how the calculator finds the line of best fit, known as the linear regression model. It uses a technique called “Least Squares Regression.” If possible, project or draw the scatter plot of the data on the front board of ...
