Identify the given statement then choose your answer inside the column below. 1. Found in a locus of point which moves so that it is always equidistant to a fixed point. 2. Properties of parabola that has a coordinate of (0,0) 3. Coefficient of e which has units above or below the vertex. 4. Coefficient of c which has units below or above the vertex. 5. Line that passes through the focus and perpendicular to the axis of the conic.

Let's break down each statement and identify its corresponding geometric or mathematical concept related to conic sections:

1. **"Found in a locus of point which moves so that it is always equidistant to a fixed point."**  
   **Answer:** Circle  
   - A circle is the locus of points that are equidistant from a fixed point, which is the center.

2. **"Properties of parabola that has a coordinate of (0,0)."**  
   **Answer:** Standard Form of a Parabola  
   - The properties of a parabola with vertex at the origin (0,0) include its equation in the form \( y = ax^2 \) or \( x = ay^2 \), depending on its orientation.

3. **"Coefficient of e which has units above or below the vertex."**  
   **Answer:** Eccentricity (e)  
   - Eccentricity \( e \) is a parameter that defines the shape of a conic section (ellipse, parabola, hyperbola). For a parabola, \( e = 1 \), and it controls the spread of the curve relative to its vertex.

4. **"Coefficient of c which has units below or above the vertex."**  
   **Answer:** Focus Distance (c)  
   - The coefficient \( c \) refers to the distance from the vertex to the focus of a conic section (for instance, in parabolas, ellipses, or hyperbolas).

5. **"Line that passes through the focus and perpendicular to the axis of the conic."**  
   **Answer:** Directrix  
   - The directrix is a line that is perpendicular to the axis of a parabola and helps define the curve along with the focus.

Would you like further details on any of these answers or examples to clarify? Here are five related questions:

1. What is the general equation of a circle in terms of the center and radius?
2. How does eccentricity \( e \) differ for ellipses and hyperbolas?
3. Can the vertex form of a parabola include horizontal translations?
4. What is the relationship between the focus and directrix in defining a parabola?
5. How does the distance to the focus (c) affect the shape of an ellipse?

**Tip:** In parabolas, the distance from any point on the curve to the focus is equal to the distance from the point to the directrix.
