Question

Draw the graph for each linear equation given below:
$y+6=0$.

Answer 1

$y+6=0=>y=-6$
In the linear equation $y=-6$, there is no term for $x$. This
means, that $x$ can take any value. Points lying on the line $y=-6$
can be $(0,-6),(3,-6)$ or $(-2,-6)$.
Plotting these points on
the graph paper and joining them, we get the graph for $y=-6$.
