Given Line Eqn
In ,
Let Fy=0:
--->
, x-Intercept (4/5,0)
Let Fx=0
--->
, y-Intercept (0,4/3)
In ,
Let Fy=0:
--->
, x-Intercept
Let Fx=0:
--->
,y-Intercept
As we see the graph,
---> is perpendicular to
To check, we know the Slope of one line is negative reciprocal of the other,. We'll see:
In , 5x+3y=4 ---> --->
,
In , 3x-5y=3 ---> --->
,
Verifying,
*The two lines are perpendicular (Answer)
Thank you,
