1. Solving System of Linear Equations
Graphing, Substitution, and Elimination methods

2. Sketch the graph the following linear equations
Warm-up
Sketch the graph the following linear equations
2. Y= -⅗x +2 1.
Y= ⅔x -4

3. System of Linear Equations
Two or more linear equations together in once coordinate plane
y = 2x-3
(2,1)
y = x-1

4. Your Turn!
(-1,4)
y = -4x
y = x+5

5. Your Turn again!
y = -½x + 2
(-2,3)
y = -3x - 3

6. Special Types of Systems

No solution

7. Practice Identify the number of solutions for each graph
Infinitely many solutions
One solution
NO solution
