Bellwork had students write and solve systems of linear equations.

The remainder of the period we began discussing Systems of Linear Equations.  Students were reminded of how to solve these systems by graphing then how to tell the number of solutions without graphing (sec 3-1).

Hwk #10 is due tomorrow:  Pages 120-121, Problems 7, 18-20, 27-29, 33 (graph paper must be used to solve by graphing)

No bellwork today.

Students were given Test #1.

No homework is due or was assigned .

Bellwork reviewed using the graphing calculator to find a Linear Regression equation for some data and using this equation to find some missing values.  It also reviewed Domain, Range, and solving Absolute Value Inequalities.

Hwk #9 is due today.

The remainder of the period students reviewed for tomorrow’s Test.

Bellwork had students create a scatter plot from a table of data.  They were to then draw a trendline and use this trendline to predict missing values then write an equation for the trendline.

The remainder of the period students learned about Linear Regression and Correlation Coefficient (Sec 2-4).  Students were shown how to use technology (graphing calculator, spreadsheet software, and websites) to make a scatter plot, find the equation of the trendline, and to find the correlation coefficient.

Hwk #9 is due tomorrow.
