If $(2, -3)$ is a solution of the equation $3x + ky = 18$,find the value of $k$.

The graph of the linear equation $5x - 3y = 20$ intersects the $x$-axis at:

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 $x-y+2=0$.

For the equation $5x + 3y = 90$,if $x = 12$,then $y = \dots$

Write four solutions for the following equation: $2x + 3y = 7$.

Draw the graph of the equation represented by a straight line which is parallel to the $x$-axis and at a distance $3$ units below it.
