Question 771455
Line 1)
Gradient = y2-y1/x2-x1
Gradient = 5 - 3/2 - 0
Gradient = 2/2 = 1
Line 2)
Gradient = y2-y1/x2-x1
Gradient = 3 -(-4)/-3 - 5
Gradient = 7/-8
For two lines to be parallel
gradients must equal one another
m1 = m2
For two lines to be perpendicular
to one another, their gradients 
must multiply together to give -1
m1*m2=-1
These lines are neither parallel or 
perpendicular.
Hope this helps.
