Answer:
Therefore,
Slopes are Equal, Hence the Lines are not Perpendicular.
Step-by-step explanation:
Given:
.......Equation ( 1 )
.......Equation ( 2 )
Comparing with,
......General Slope point form
Where m =slope
We get
For Equation ( 1 )
For Equation ( 2 )
Hence,
Therefore, Slopes are Equal Hence the Lines are Parallel not Perpendicular.
For Perpendicular we require
Therefore,
Slopes are Equal, Hence the Lines are not Perpendicular.
