Question

the graphs of the relations x=-2 and y=-5 intersects at which point?

Answer 1

(-2,-5)
:)

Answer 2

at the point defined by these coordinates: (-2, -5). that is the only point which satisfies both equations and therefore the point of intersection.

Answer 3

x = - 2 is a vertical line through x = -2. (vertical = up and down).
y = -5 is a horizontal line through y = -5 (horizontal = left and right).
They meet at the point (-2,-5).

If you go to http://www.wolframalpha.com and type
plot x = - 2 , y = -5 from x = - 6 to 6, y = -6 to 6

You will get the attached picture.
Hope this helps! :)
