1st, 2nd, 3rd Hours:
Bellwork reviewed using the graphing calculators to make a scatter plot and find a regression equation to fit the data.
The remainder of the period we continued discussing scatter plots and regression equations. Students were also shown how to use a system of equations and matrices to find the equation of a parabola that passes through three points.
Hwk #15 is due tomorrow.
