Exercise 10 Page 159

The first thing to notice about this equation is that it is missing a variable term. Let's try to rewrite it in standard form, $Ax+By=C,$ using $0$ as the coefficient for our missing variable. Let's graph using a table. First select some arbitrary values from the domain, then substitute them for $x$ in the given equation. Solving for $y$ will give us the corresponding values from the range.

$x$	$0x+y=\text{-}1$	Simplify
$0$	$0(0)+y=\text{-}1$	$y=\text{-}1$
$2$	$0(2)+y=\text{-}1$	$y=\text{-}1$
$4$	$0(4)+y=\text{-}1$	$y=\text{-}1$

Using these $x$ and $y$ values as $(x,y)$ coordinate pairs, we can plot the points. Connecting these points with a line will give us the graph of the equation.
