the given equation has a slope of -2,,a line parallel to this will have the same slope,,a line perpendicular to this will have a slope that is the negative reciprocal of -2..or 1/2

the equation of a line containing (1,5) with a slope of -2 is

the equation of a line containing (1,5) with a slope of 1/2 is
