Bellwork reviewed graphing two lines to find the solution to a system of linear equtions and to find when two companies charge the same amount for phone service by writing an equation for each company’s charges.
Hwk #13 is due today.
The remainder of the period we discussed Sec 7-1, Solving Systems of Linear Equations by graphing and finding the number of solutions without graphing.
We then began discussing Sec 7-2, Solving a System of Linear Equations using Substitution.
