2) through: (4, 3), parallel to x = 0

Explanation:

Step1: Analyze the line (x = 0)

The line (x=0) is a vertical line (parallel to the (y -)axis). A line parallel to a vertical line is also vertical.

Step2: Determine the equation of the vertical line passing through ((4,3))

The equation of a vertical line passing through the point ((a,b)) is (x=a). Since the line passes through ((4,3)), the equation is (x = 4).

Answer:

(x=4)
