I believe the answer is "perpendicular line". Forgive me if I'm wrong :)
The x and y axes intersect at the point of origin at (0, 0) on the Cartesian plane
An x-intercept is the point where a function intersects the x-axis on a Cartesian coordinate plane. For example, if the graph of a parabola is plotted and the graph intersects the x-axis on the coordinate plane, the point(s) where the graph intersects the x-axis are the x-intercepts for that function.
The perpendicular bisector of the line XY will meet it at its midpoint at right angles.
BC and DE
Yes. There can be a line perpendicular to the given line at every point on it, and you know how many different points there are on it ...
A plane intersects a line at a point, and i plane intersects another plane at a line.

This point is the origin.

You a goofy shoty B.

The radius of the circle that is perpendicular to a chord intersects the chord at its midpoint, so it is said to bisect the chord.
Yes.
tangent
It is the point where the line intersects the y-axis.
