Intersecting lines
A tangent line touches the circumference of a circle exactly at one point.

No. A pair of linear equation can have 0 solutions (they are parallel), or one solution (they cross at one point) or an infinite number of solutions (they represent the same line).
Yes. Remember that the intercepts are where the line crosses the axis. Since each axis is also a line this is the same as saying that any two lines that cross, cross at only one point. I wonder if a curved line could perhaps cross an axis twice.
Tangent
point of intersection.
It is a Geometry Theorem. "A line and a point not on the line lie in exactly one place" means what it says.
Shapes with an irregular cross-section.
Definition: a tangent is a line that intersects a circle at exactly one point, the point of intersection is the point of contact or the point of tangency. a tangent is a line that intersects a circle at exactly one point, the point of intersection is the (point of contact) or the **point of tangency**.
