The document provides a quick review for a quiz on writing equations of lines and solving systems of equations using elimination. It includes 4 problems writing equations of lines, instructions to complete circled problems on a handout after the quiz, mentions of partner points, and 3 sample problems solving systems of equations using elimination.

1. Day #5: Quick Review Complete the problems below as a quick review
before your quiz.
1. Write the equation of the line with slope ‐3 that passes
through the point (‐2, 5).
2. Write the equation of the line through (2, 1) and (‐4, 6).
3. Write the equation of a horizontal line through (3, 4).
4. Write the equation of a vertical line through (3, 4).

4. Section 4.12: Solving Systems: Elimination
Ground Rules: If x = 3 and y = 8, what does x + y equal?
Key Idea: We can add equations together and the
result is still valid.
Solving Systems with Elimination uses this idea!
Elimination Ex. #1: Solve the system: x + y = 10
x ‐ y = 3
Elimination Ex. #2: Solve the system: 6y ‐ 4x = 3
4x + 2y = 1

5. Elimination Ex. #3: Solve the system: 3x + 2y = 11
3x ‐ 5y = 25
