C is the answer!
Step-by-step explanation:
The slope of points P and Q is,
m=y2-y1/x2-x1
substitute the numbers in the equation above,
m=2-3/4-8
m=-1/-4
m=1/4
The slope of points R and S,
m=-2-(-5)/-1-(-5)
m=-2+5/-1+5
m=3/4
Remember, that parallel lines have the SAME SLOPE!
So no, the lines are not parallel!
