Answer:
x=-7
Step-by-step explanation:
the equation for the vertical line that contains point E(–7, 7)
General equation of a vertical line is x= some number
The given point is (x,y)
point E (-7,7) where [tex]x=-7 , y=7[/tex]
To get the equation of the vertical line
x= value of x in the given point
[tex]x=-7[/tex] is the equation of the vertical line
