Write an equation parallel to the y-axis through the point (−6, 3)

An equation parallel to the y-axis represents a vertical line. The equation of a vertical line is of the form x = k, where k is the x-coordinate of any point on the line.

Since we want an equation passing through the point (-6, 3), the x-coordinate of this point would be the constant in our equation. Hence, the equation parallel to the y-axis through the point (-6, 3) is x = -6.
