Answer:
B. slope = Undefined, x = 3
Step-by-step explanation:
The equation of a vertical line always takes the form x = k, where k is any number and k is also the x-intercept .
So the slope for this is undefined, since it's just a vertical line so, since the equation is x = k. If it's horizontal then it's 0.
the best fit for this is the first option slope = undefined, x = 3.
slope: Undefined
x-intercept: 3
