what are the ordered pairs for x - 5 = 0

Answer 1

You can solve for x by adding 5 to both sides, giving you x=5

If you are not given any other equation and this is the equation for your line then you have several points that can fall on this line. For x=5, x is always 5, so when y=0 x is 5, y = 1 x is still 5 and so on. This is a vertical line. So ordered pairs could be any value for y, and x as 5.
