## 1. Linear Equations in two Variable

Equation having two variables i.e. x and y and where the maximum power of both the variable is 1 are called linear equation in two variables.

### Solution of a Linear Equation in two variables

### When are pair of lines intersecting, coincident or parallel

For two lines: x+y+=0 and x+y+=0

Lines will be intersecting if ≠

Lines will be coincident if: = =

Lines will be parallel if: = ≠
