Answer:
x=2 would be the equation.
Step-by-step explanation:
Let's take any two points from y-axis. Like (0,4) and (0,5)
Now,
Slope (m) = (5-4)/(0-0)
= 1/0
this is undefined.
slope of parallel lines are same, so the slope of (2,-1) is also 1/0 which is undefined.
Since its undefined equation would be x = 2
