| A | B |
|---|
| consistent | cross (different slopes) |
| inconsistent | parallel (same slopes, different y-intercepts) |
| dependent | same line (same slopes AND y-intercepts) |
| solution | the point where the 2 lines intersect |
| system of equations | 2 equations with 2 variables having the same solution |
| elimination | get a pair of variables to have opposite signs of the same number then add them |
| substitution | solve one variable for x or y then substitute it into the other equation |
| let statement | representing the variables, telling what each represents |
