#### Work Step by Step

The x-intercept of the equation $x - y = -4$ can be found by substituting in $0$ for $y$ ($y$ will be zero at the equation's x-intercept). Thus: $x - 0 = -4$ $x = -4$ at the equation's x-intercept. Therefore, the equation passes through the point $(-4, 0)$. At the equation's y-intercept, $x = 0$. Thus: $0 - y = -4$ $y = 4$ at the equation's y-intercept, and the equation passes through the point $(0, 4)$. If we plot these two points and draw the line that passes through them, we will get the graph of this linear equation.
