to solve this problem you must se up an equation as +%28x2-x1%29+%2F+%28y2-y1%29+ in this case it would be +%28-2-1%29%2F%285-3%29 It gives you +-3%2F2+ which makes your slope of 1,3 and -2,5 3%2F2 The slope of a parallel line is always the same which would make it 3%2F2 as well. If it were a perpandicular line it would be the negitive inverse of that, making it -2%2F3

SLOPE OF A LINE IS (Y2-Y1)/(X2-X1) THUS WE HAVE
(5-3)/(-2-1)=2/-3 OR -2/3 IS THE SLOPE
-------------------------------------------------------------
(0-5)/(-1-1)=-5/-2 OR 5/2 OR 2.5 IS THIS SLOPE
