x=-9 for every value of y x must be -9
:this point has an x value of 6
:
therefore NO it is not on the line

The equation is the equation of a vertical line consisting of all points in with x-coordinate equal to -9. Any point with an x-coordinate of -9 is on the line. Any point with any other x-coordinate is not on the line.

By the way, you separate coordinates in an ordered pair with a comma, not a period, like this (6, -8).
