2
3
One Solution
If the lines intersect (cross), there is only 1 solution.
4
5
One Solution (by hand)
If you solve the equation and you get a solution for the variable.
6
7
No Solution (by graph)
The lines are parallel and do NOT intersect (cross).
8
9
No Solution (by hand)
When solving the equation, the result will NOT be a true statement.
10
11
Infinitely many solutions
When 2 equations are entered, but only 1 line is visible (seen).
12
13
Infinitely Many Solutions
