Check whether $(4, 0)$ is a solution of the equation $x - 2y = 4$.

Show that the points $A(1, 2)$,$B(-1, -16)$,and $C(0, -7)$ lie on the graph of the linear equation $y = 9x - 7$.

Write four solutions for the equation: $\pi x + y = 9$

Find the solution of the linear equation $x + 2y = 8$ which represents a point on:
$(i)$ $x$-axis
$(ii)$ $y$-axis

One of the solutions of the linear equation $3x + 5y = 30$ is $\ldots \ldots . .$

State whether the following statement is True or False and justify your answer:
Every point on the graph of a linear equation in two variables does not represent a solution of the linear equation.
