Determine whether the two lines are parallel perpendicular c
     Determine whether the two lines are parallel, perpendicular, coinciding, or only intersecting.  5x-6y=42  y=5/6^x-7  Choose the correct answer below.  parallel  perpendicular  only intersecting  coinciding 
  
  Solution
Answer:
The lines are given by
5x - 6y = 42 => 6y = 5x - 42 => y = (5/6)x - 7 ------ ( 1 )
and y = (5/6)x - 7 ------ ( 2 )
Since both lines are of same slope m = 5/6
Hence the lines ( 1 ) and ( 2 ) are parallel
