 Coordinate geometry Distance from a point to a line The formula that gives the distance between a point A=(m,n) and a line r:ax+by+c=0 is: Find the distance from point A(4,1) to the line r:2x-y+4=0 Find the distance between the point A=(1,-2) and the line that goes through the point P=(3,2) and which position vector is v=(-2,0) D =
