Answer:
[tex]x=4[/tex]
Step-by-step explanation:
A vertical line has an undefined slope.
A line with an undefined slope can not be written in slope intercept form, but it can be written in [tex]x=a[/tex] form, where [tex]a[/tex] is the x-intercept.
[tex]x=4[/tex] will include the point (4, -3). The line will go through any point with 4 as it's x-value.
