Hi,         

equations for the vertical and horizontal lines passing through the point (9,7)

  x = 9 (blue) and y = 7

A vertical line that passes through the point (9,7) will consist of a set of ordered pairs such that the x-coordinate is always 9, ergo:



Which is just another way of saying give me the set of all ordered pairs where the x-coordinate is 9 and I don't care what the y-coordinate is.

Using similar logic you should be able to handle the horizontal line part of this question.
