Hello and Good Morning/Afternoon:
Let's take this step-by-step:
Let's find the slope:
[tex]\hookrightarrow \text{Slope} = \frac{y_2-y_1}{x_2-x_1}=\frac{1--3}{-4--4} =\frac{4}{0}=[/tex] undefined
If the slope is undefined:
⇒ the equation is of the form 'x = a'
[tex]\hookrightarrow \text{a is the x-coordinate shared by both coordinates}[/tex]
Thus the equation is x= -4
Answer: x= -4
Hope that helps!
