Write the equation of the line passing through (–6, –3) and (–6, 1).?

Answer 1

x = - 6 is the equation. It is a vertical line parallel to y axis passing through x = - 6.

Answer 2

The answer is x = -6.

If you plot out the two points and draw a line through them, the line will be 6 spaces to the LEFT of the vertical y-axis. It's the opposites for both, so since the x-axis is horizontal it will take the place of the vertical line. The y, being vertical, takes its place with the horizontal. Yeah, confusing.
