## awesomeness123 2 years ago 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).

1. awesomeness123

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

5. saifoo.khan

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

6. awesomeness123

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

7. saifoo.khan

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

8. awesomeness123

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

9. saifoo.khan

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