Final answer:
The 'anchor point' in a coordinate system is the origin, represented by the ordered pair (0,0). Additional details describe the use of coordinates and vectors within this system.
Step-by-step explanation:
The question refers to a coordinate system, which is a two-dimensional number line where each point is uniquely specified by a pair of numerical coordinates, which are the signed distances to the point from two fixed perpendicular oriented lines, measured in the same unit of length. The 'anchor point' in this context would likely refer to the point where these two lines intersect, which is known as the origin. The origin is always at the ordered pair (0,0).
When extended to three dimensions, this system includes a z-axis, and points in space are determined by an ordered triplet (x, y, z). The vector described in Figures 3.24, 3.26, and 5.18 has both x and y components, Ax and Ay, which help determine its position and direction from the origin in a two-dimensional plane.
In terms of graphing data or determining the position of vectors in a plane, the question emphasizes the importance of both the coordinate system and the understanding of vectors and their components.
