6. Example 1 No Solution & infinitely many solutions
Solve each system of equations by graphing. y = -x + 1 y = -x + 3

7. Example 2 No Solution & infinitely many solutions
Solve each system of equations by graphing. y = 2x + 4 1/2y – x = 2

8. Notes

9. Example 3 No Solution & infinitely many solutions
Solve each system of equations by graphing. y = x + 4 y = x

10. Example 4 No Solution & infinitely many solutions
Solve each system of equations by graphing. y = ½ x – 1 x – 2y = 2

11. Example 5 No Solution & infinitely many solutions
Solve each system of equations by graphing. y = -x – 3 2x + 2y = -6

12. Example 6 No Solution & infinitely many solutions
Solve each system of equations by graphing. y = 2x y = 2x - 4

13. Notes When the graphs of a system of equations have:
* Different Slopes>>>Exactly 1 Solution
* Same Slope, Different Y – Intercepts>>>
No Solution
* Same Slope, Same y – intercept>>>
Infinitely Many solutions
