Question

I WILL FAN/GIVE YOU A MEDAL/WRITE A TESTIMONIAL FOR YOU IF YOU HELP ME!! ANSWERS BELOW~!

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

Answer 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 5

A line parallel to: y = x + 5 will have same slope.

Answer 6

so do i have to like use y-y1=m(x-x1) for all of them to find which one has the same slope

Answer 7

Yes.
One equation can be found out by:
y - (-1) = 1(x-(-2))

Answer 8

then in case there is two with the same slope, the reciprocal will be the slope of the perpendicular line right?

Answer 9

The first one will be with same slope.
The second one will be the reciprocal one. Which will be -1.
