LINEAR EQUATION IN TWO VARIABLES

1. Definition: Any equation which is the form of ax+by+c=0, where a,b and c are real numbers is said to be linear equation in two variables

2. Linear equation in two variables has infinitely many solutions

3. The graph of every linear equation in twovariables is a straight line

4. x=0 is the equation of the y-axis and y=0 is the equation of the x-axis

5. The graph of x=a is a straight line parallel to the y-axis

6. The graph of y=a is a straight line parallel to the x-axis

7. An equation of the type y=mx represents a line passing through the origin
