well, you know that
tan π/6 = 1/√3
using that as your reference angle, and knowing that for a triangle in standard position tan(u) = y/x, you must have either
-1/√3 (QII)
or
1/-√3 (QIV)
So, for the given domain, that means the solutions are
x = 5π/6, 11π/6, 17π/6
List all points on the graph of y=tanx on the interval [π/2,3π] that have a y-coordinate of -1/radical3
(Type ordered pair)
Please teach me and show step by step work so i can learn. Thank you.

Thank you steve. I understand. But, in the direction, it said to type ordered pair. So how am i suppose to know what y is?.
Did you not read the problem?
points on the graph of y=tanx on the interval [π/2,3π] that have a y-coordinate of -1/radical3
geez! y = -1/√3 !!
at each of those points. So, knowing the x values, the pairs are
(5π/6,-1/√3), ...
