If the point $(3,4)$ lies on the graph of $3y = ax + 7$,then find the value of $a$.

Write whether the following statement is True or False. Justify your answer:
The graph given below represents the linear equation $x=3$.

Write whether the following statements are True or False? Justify your answers.
$(i)$ $ax + by + c = 0$,where $a, b$ and $c$ are real numbers,is a linear equation in two variables.
$(ii)$ $A$ linear equation $2x + 3y = 5$ has a unique solution.
$(iii)$ All the points $(2, 0), (-3, 0), (4, 2)$ and $(0, 5)$ lie on the $x$-axis.

If a linear equation has solutions $(-2, 2), (0, 0)$ and $(2, -2)$,then it is of the form

State whether the following statement is True or False. Justify your answer:
The coordinates of points in the table:

$x$	$0$	$1$	$2$	$3$	$4$
$y$	$2$	$3$	$4$	$-5$	$6$

represent some of the solutions of the equation $x-y+2=0$.

Draw the graph of the linear equation $3x + 4y = 6$. At what points does the graph cut the $x$-axis and the $y$-axis?
