What line on a circle only intercepts once?

a line can only have 1 y-intercept .

No. The equator is a line of latitude. The equator is the only line of latitude that is a great circle.

A. If the line segment touches two points on the circle it is called as: 1. secant; if the line extends outside the circle. 2. chord; if the line is present only within the circle. B. If the line segment touches one point on the circle AND the center of the circle AND is present only within the circle it is called as: radius.

The Tangent Line to Circle Theorem states that a line is tangent to a circle if and only if it's perpendicular to the circle's radius.

If you mean a line that gous from the center of a circle to the edge of the circle, that is a radius.

Is calleda tangent line. Is called a tangent line

A tangent of a circle is a straight line that touches the circle at only one point.

They can be: a sector, a segment and a tangent

tough to answer, but if slope is only provided then it should intercept at (0,0). Such as, y=3x, that intercepts at 0.

The tangent line. A secant line hits the circle in two places and forms a cord, but the tangent line only hits the circle in one point and is always perpendicular to the radius of the circle which exists at that point.

a tangent is a line that touches the circle at only ONE point

The radius of a circle is one half of the circle's diameter, any line going from the center of the circle to the circle itself. A line connecting other points on a circle (or on any curve) is called a chord.

a semi-circle only has one line of symmetry

That is a tangent line.

A triangle with only two of its sides equal. Also a semi-circle or any incomplete circle.

The circumference of a circle is a line. Because it is a line it has no area, only length. So the area of the circumference cannot exist!

a tangent to the circle

The tangent line only touches the outside of a circle at one given point. So an outside line perpendicular to the circle's diameter at 90 degrees should do.

Well the radius is only half of the line on the circle the circumference is all around

Regardless of where you mark two points on a circle, there's only one possible line segment between them. It's called a "chord" of the circle.

No, if the vertex of the parabola is (0, 0) it will only have one x intercept. The parabola might have zero x intercepts as well. For example: Y= x^2 + 1 would never touch the x line.

A circle doesn't really have an edge, per se. But I think what you are referring to is a tangent. A tangent is a line that touches the perimeter of the circle at only one point. (see related link)

Only one endpoint? if two, it's a diameter...

No. A chord is a line that joins two points on the circle. A radius touches only one point on the circle.

The only diameter would be a line segment connecting the end points of the half-circle arc.
