To draw the graph of linear equation in two variables, we need to draw a table to write the solutions of the given equation, and then plot them on the Cartesian plane.

By joining these coordinates, we get the line of that equation.

- The coordinates which satisfy the given Equation lies on the line of the equation.
- Every point (x, y) on the line is the solution x = a, y = b of the given Equation.
- Any point, which does not lie on the line AB, is not a solution of Equation.

**Example:**

Draw the graph of the equation 3x + 4y = 12.

**Solution:**

To draw the graph of the equation 3x + 4y = 12, we need to find the solutions of the equation.

Let x = 0

3(0) + 4y = 12

y = 3

Let y = 0

3x + 4(0) = 12

x = 4

Now draw a table to write the solutions.

x | 0 | 4 |

y | 3 | 0 |

Now we can draw the graph easily by plotting these points on the Cartesian plane.
