##### Pair of Linear Equations in Two Variables – Notes

**Graphical Method of Solution **

The general form of a pair of a linear equations in two variables x and y are:

a_{1}x + b_{1}y + c_{1} = 0 and a_{2}x + b_{2}y +c_{2} =0

a_{1}, a_{2}, b_{1}, b_{2}, c_{1}, c_{2 }are all real numbers and a_{1}^{2} + b_{1}^{2 }¹0 and a_{2}^{2 }+b_{2}^{2} ¹ 0

Solving a pair of linear equation graphically:

- Frame the pair of linear equations based on the problem
- Find ordered pair (x, y) satisfying the equations
- Plot the pints obtained on the graph to find the solutions

Consistent solution: a pair of linear equations having unique or infinite solutions.
