Plotting Vectors

Using initial and terminal points

Note: Problems 14.1–14.5 refer to vector v, which has initial point P = (–2,3) and terminal point Q = (5,1).

14.1    Plot v in the coordinate plane.

Vector v begins at point P = (–2,3) and extends to point Q = (5,1), where it terminates, as illustrated in the following graph. Note that the initial and terminal points are not explicitly depicted on the graph of the vector.

In other words, just draw an arrow whose pointy end is the terminal point. Don’t draw dots on the graph to represent the initial and terminal points of the vector.
