The graph of the equation $0x + 3y = 21$ is perpendicular to which axis?

Express the following linear equation in the form $ax + by + c = 0$ and indicate the values of $a, b$ and $c$ in each case:
$x = \frac{2}{5}y + 10$

Write the following as an equation in two variables: $8 y - 15 = 0$.

The following observed values of $x$ and $y$ are thought to satisfy a linear equation. Write the linear equation:

$x$	$6$	$-6$
$y$	$-2$	$6$

Draw the graph using the values of $x$ and $y$ as given in the above table.
At what points does the graph of the linear equation:
$(i)$ cut the $x$-axis and
$(ii)$ cut the $y$-axis?

Any point on the $x$-axis is of the form

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.
