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).
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

A line parallel to: y = x + 5 will have same slope.
so do i have to like use y-y1=m(x-x1) for all of them to find which one has the same slope
Yes. One equation can be found out by: y - (-1) = 1(x-(-2))
then in case there is two with the same slope, the reciprocal will be the slope of the perpendicular line right?
The first one will be with same slope. The second one will be the reciprocal one. Which will be -1.
