P-Level P1. The vector (2, 7) moves points along a line L. Identify a vector that has the same length as (2,7) and that moves points along a line that is perpendicular to L. P2. Here is the line L, the point p, and the point m: P m q The point p does not lie on L. The point m is the point on L that is closest to p. The vector V that is given by m p is given in coordinates as V=il
