Linear Equations in Two Variables

Chapter Notes

Top Definitions

1. An equation of the form ax + by + c = 0, where a, b and c are real numbers, such that a and b are not both zero, is called a linear equation in two variables.

2. A linear equation in two variables is represented geometrically by a straight line the points of which make up the collection of solutions of equation. This is called the graph of the linear equation.

Top Concepts

1. A linear equation in two variables has infinitely many solutions.

2. The graph of every linear equation in two variables is a straight line.

3. x = 0 is the equation of the y – axis and y = 0 is the equation of the x–axis.

4. The graph of x = k is a straight line parallel to the y –axis.

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

6. An equation of the type y = mx represents a line passing through the origin, where m is a real number.

7. Every point on the line satisfies the equation of the line and every solution of the equation is a point on the line.

8. The solution of a linear equation is not effected when:

(i) The same number is added or subtracted from both the side of an equation.

(ii) Multiplying or dividing both the sides of the equation by the same non zero number.
