Answer:
Therefore,
 and
 and
 are not Perpendicular.
 are not Perpendicular.
Explanation:
Given:
 ............................Equation of line( 1 )
 ............................Equation of line( 1 )
 ............................Equation of line( 2 )
 ............................Equation of line( 2 )
Solution:
So the Equations are written in

Where m is the slope of the line
On Comparing we get


So for the lines to be Perpendicular.
Product of slopes = - 1
m1 × m2 = -1
So Product of slopes of the given lines are

Which is not equal to -1
Therefore,
 and
 and
 are not Perpendicular.
 are not Perpendicular.
