Answer
Missing terms in order are:
$$\boxed{-2};~\boxed{\text{does not}};~\boxed{\text{undefined}}$$
$$\boxed{\frac12};~\boxed{\text{does not}};~\boxed{0}$$
Work Step by Step
$$x+2=0$$
$$x=-2$$
It is a vertical line that crosses $x$-axis at $-2$.
Hence, $x$-intercept is $-2$.
It does not have $y$-intercept since it is parallel to $y$-axis.
Slope of the vertical line is undefined.
$$4y=2$$
$$y=\frac12$$
It is a horizontal line with $y$-intercept $\frac12$.
It does not have $x$-intercept since it is parallel to $x$-axis.
Slope of the horizontal line is $0$.
