graph ABC with the vertices A(-3,4), B(0,2) and C(-2,-5) and its image after a reflection in the line y=-1

How do you write y-10=2 (x-8) in standard form

Ithink i know it but i want to be sure so can you me out ?

Which lines are parallel? justify your answer. lines p and q are parallel because same side interior angles are congruent. lines p and q are parallel because alternate exterior angles are congruent lines l and m are parallel because same side interior angles are supplementary lines l and m are parallel because alternate interior angles are supplementary.
