Question

Need some assistance !
Select the equations that are parallel and perpendicular to y = x + 5 and that pass through the point (-2, -1).
Choose one answer.
a. parallel: y = -x - 1
perpendicular: y = x + 2
b. parallel: y = x - 1
perpendicular: y = -x + 1
c. parallel: y = x + 1
perpendicular: y = -x - 3
d. parallel: y = 2x - 2
perpendicular: y = -2x - 1

Answer 1

parallel lines have the same slope

perpendicular lines have negative reciprocal slopes

Answer 2
