Write each of the following as an equation in two variables
$3 y=-11$
$0 x+3 y+11=0$
The equation $x=7,$ in two variables, can be written as
The graph of the linear equation $2 x+3 y=6$ cuts the $y$ -axis at the point
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.
The point of the form $(a,-a)$ always lies on the line
If $(-2,-3)$ is a solution of equation $a x-5 y=21,$ then $a=\ldots \ldots . .$
