How do you graph the lines using slope-intercept form #x= -2#?

The slope for #(x=-2)# is undefined and as such you can not really use the slope-intercept form.

Explanation:

The slope-intercept form is
#color(white)("XXX")y=mx+b# for a line with slope #m# and y-intercept #b#

No such equation exists that is equivalent to #x=-2#.

#x=-2# is a vertical line passing through the X-axis at #(-2)#
It has an undefined (infinite) slope and does not cross the Y-axis (there is no y-intercept).
