ANSWER: x=1

Answer 1

explain

Answer 2

Same thing as last time...except a vertical line has the equation \[\large x = \]

it can only go through 1 point on the 'x' axis...so we need to make it the 'x' point of your coordinate (1 , -1)

the x coordinate is 1...so our equation will be \(\large x = 1\)
