##### Important Terms on Linear Equations

- An algebraic equation is a statement of equality of algebraic expression involving one or more variables.
- An equation which can be put in the form ax + by + c = 0, where a, b and c are real numbers (a and b together cannot be zero) and x, y are variables, is called a liner equation in two variables.
- A linear equation in one variable (say x) can be written as linear equation in two variables, by taking coefficient of other variable (say y) as zero.

- The solution of a linear equation is not affected when
- The same number is added to (or subtracted from) both sides of the equation.
- Both sides of the equation are multiplied (or divided) by the same non-zero number.

- The graph of every linear equation in two variables is a straight line and every point on the graph (straight line) represents a solution of the linear equation.
- Every solution of the linear equation cab be represented by a unique point on the graph of the equation.

x = 0 is the equation of the Y- axis and y = 0 is the equation of the X-axis. - The graph of x = a represents a straight line parallel to the Y-axis and the graph of y = a represent a straight line parallel to the X-axis.
- An equation of the type y = mx represents a straight line through the origin.
