Answer:
The slope of line MN is two thirds,
The slope of line RS is negative three-halves
and line RS is perpendicular to both line MN and PQ
Step-by-step explanation:
For the first two, I found the slope using the slope formula, and I know the third one is correct because that is what it says in the very beginning.
Hope this helped, sorry if it is a little hard to understand, it was pretty hard to understand. :)
