Math 10C: Week 15 - Linear Systems, Substitution, Elimination, Chapter 6 Exam

This week we are: Working on our understanding of Linear Systems, two linear equations that have a common point of intercept

I will: solve for linear systems using graphical analysis I will: solve for linear systems using the substitution method I will: solve for linear systems using the elimination method I will: define linear systems as solvable, unsolvable and infinite solutions I will: determine which method works best for me.

I can: graph 2 linear equations and find the point of intercept I can: substitute and equation for x or y and solve for the other unknown I can: eliminate a variable by multiplying an equation or two equations by a common factor I can: determine how many solutions exist when looking at two linear equations, either by assessing the existing equation or by modifying it.

Monday

1.  Formative Assessment 6.1 Graphical Analysis of Linear Systems

2.  We will go over how to do substitution of linear systems.  We will go over two methods, substitution with brackets or equaling two equations to each other.

3.  Students will demonstrate their understanding using the simple examples and then move on to the more advanced sheet.

4.  Students will have time to work on practice worksheets.

Tuesday
