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

Parallel => same slope
Perpendicular => slope = -1/(slope given in the equation).

You can eliminate two options from these information.

Then, 'pass through the point (-2, -1). '
Plug the values into the equation and see if the left side is equal to the right side. If so, that's the equation.

Answer 2

is the first one it

Answer 3

How did you get that?

Answer 4

i think its the second one but i can try again to make sure..

Answer 5

can u plz help and tell me the answer very important
