Show that the vector v = ai +bj is perpendicular to the line ax + by = c by establishing that the slope of v is the negative reciprocal of the slope of the given line. Use the above to find an equation for the line through P perpendicular to v. Then sketch the line. Include v in your sketch as a vector starting at the origin. When P(-2,-7),v = -2i +j
