Question 1126443: Lines l1 and l2 pasa through the given points. Determine if l1 and l2 are parallel, perpendicular, or neither.
l1: (10/9,0) and (0,10/3)
l2: (35/18,0) and (0, 35/6)
How do you solve the fractions? I am quite confused. Thank you!

Compare the slopes
(11)
+%28+10%2F3+-+0+%29+%2F+%28+0+-+10%2F9+%29+=+%28+10%2F3+%29%2A%28+-9%2F10+%29+
+%28+10%2F3+%29%2A%28+-9%2F10+%29+=+-3+
(12)
+%28+35%2F6+-+0+%29+%2F+%28+0+-+35%2F18+%29+=+%28+35%2F6+%29%2A%28+-18%2F35+%29+
+%28+35%2F6+%29%2A%28+-18%2F35+%29+=+-3+
They have the same slope, so the lines are parallel
