How to graph $x-y=1$?

Larissa Pacheco

Graph:
$x-y=1$
X-intercept: value of $x$ when $y=0$
Substitute $0$ for $y$ and solve for $x$.
$x-0=1$
$x=1$
The x-intercept is $\left(1,0\right)$. Plot this point.
Y-intercept: value of $y$ when $x=0$
Substitute $0$ for $x$ and solve for $y$.
$0-y=1$
$-y=1$
Multiply both sides by $-1$. The signs will change as a result.
$-1\left(-y\right)=1×-1$
$y=-1$
The y-intercept is $\left(0,-1\right)$. Plot this point.
Put a line through each of the points.
