Final answer:
The equation of the line parallel to the y-axis that passes through the point (-8, 3) is x = -8.
Step-by-step explanation:
The equation of a line that is parallel to the y-axis and passes through a specific point on a coordinate plane can be written in the form of x = a, where a is the x-coordinate of the point through which the line passes. In this case, the given point is (-8, 3), so the line passes through x = -8.
Therefore, the correct equation of this line is x = -8.
