The equation of the $x$-axis is of the form:

Express the linear equation $3x + 2 = 0$ in the form $ax + by + c = 0$ and indicate the values of $a$,$b$,and $c$.

Draw the graph of the linear equation in two variables: $x + y = 4$.

The graph of the equation $3x = 10$ is parallel to which axis?

Draw the graph of the linear equation in two variables: $3 = 2x + y$

State whether the following statement is True or False. Justify your answer:
The graph of every linear equation in two variables need not be a line.
