Answer
Slope: $m=-1$
$x$-intercept: $(4,0)$
$y$-intercept: $(0,4)$
Work Step by Step
$y=4-x$
Rearrange the equation of this line by writing $x$ first:
$y=-x+4$
This line is now in slope-intercept form, which is $y=mx+b$, where $m$ is the slope of the line and $b$ is its $y$-intercept.
Comparing the given equation to the slope-intercept form, it can be seen that $m=-1$ and $b=4$
The slope of the given line is $m=-1$ and its $y$-intercept is the point $(0,4)$
To find the $x$-intercept, set $y$ equal to $0$ and solve for $x$:
$0=-x+4$
$x=4$
The $x$-intercept of the given line is the point $(4,0)$
