| Solve the system of linear equations by graphing {x+y=5, x+y=6 | There is no solution.
(The slopes are the same, but the y-intercepts are different, resulting in 2 parallel lines).
🗑

| Solve the system of linear equations by graphing {x=-5, y=8 | The solution of the system is (-5,8).
🗑
|

| Solve the system of linear equations by graphing {y-5x=-2, 1-x-2y=4 | Since both lines are identical, there are infinitely many solutions.
🗑
