    Vectors

    Here is the question:

    Suppose you're taking a walk on the plane, starting at the point (-3, 0) and later arriving at the point (-2, 3). If you began walking in the direction of the vector and changed direction at only one point, at which point you turned at a right angle, then what are the coordinates of the point where you make the turn?

    I'm not quite sure how to go about this question. Any help would be appreciated.

    the line that passes thru (-3,0) with the given direction vector is

    y = \frac{1}{3}(x+3)<br />

    find the equation of the perpendicular line that passes thru (-2,3) ... then find their intersection.
