Question

Select the equations that are parallel and perpendicular to y = x + 5 and that pass through the point (-2, -1).

parallel: y = -x - 1
perpendicular: y = x + 2

parallel: y = x - 1
perpendicular: y = -x + 1

parallel: y = x + 1
perpendicular: y = -x - 3

parallel: y = 2x - 2
perpendicular: y = -2x - 1

Answer 1

perpendicular lines have negative reciprocal slopes
parallel lines have the same slope

that being said, determine the perpendicular and parallel slopes
then use point slop formula and convert to slope intercept form for both slopes

Answer 2

so b?

Answer 3

no idea, i didnt do the problem,

if those are the 2 equations you got when following my steps, then yes
if not, then no
