Consider the points in the plane P(10, 8) and Q(-1, -7) Sketch the vector PQ in 2-space. Clearly label each point and the vector. Find the position vector (the vector with initial point at the origin) that corresponds to the vector PQ and sketch the vector on your picture above. Clearly label each point and the vector. Find a vector perpendicular to PQ and call it v. Sketch it on the plane above. Clearly label each point and the vector and show that it is perpendicular.

Coordinate Geometry

Coordinate geometry, also known as analytic geometry or Cartesian geometry in classical mathematics, is a type of geometry that is studied using a coordinate system. Coordinate geometry is a branch of mathematics that describes the position of points on a plane using an ordered pair of numbers called coordinates.
