Day 78

Exam Review: A couple of questions from each section of the review were taken up and then students were given the rest of class time to work.

Day 77

Exam Review: Students were given booklets of review questions

Day 76

Page 200: #3-4

Day 74

Word Problems: Hint each word problem gives you two equations, all you have to do is find the solution to the system of linear equations.

Day 73

5.4 Elimination

Note: Elimination is essentially either adding the equations together or taking one equation away from the other. The goal is to eliminate one of the variables so you can solve for the other one.

Assignment: page 193: #1-12 and 17-20

Day 72

Review of 5.2 and 5.3

Page 198: #3-10

Day 71

Solving Linear Systems by Substitution

Rules:
1. Isolate a variable in one of the equations
2. Substitute the value of the isolated variable into the other equation
3. Solve the equation
4. Once you have solved for one of the variables, you substitute its value back into one of the original equations.
5. Check: plug the point into both equations to make sure that it satisfies both.

Day 70

Group work: Posters with points of intersection questions on them.

Day 69

Assignment: page 179: #17 to be handed in

Day 68

Assignment: Page 179: #11-16

Day 67

Solutions to linear systems(Finding a Point of Intersection graphically)

Note: A point of intersection is also known as a solution. The solution satisfies both equations and it is the point of intersection when the two equations are graphed.
