Step-by-step explanation:




The circumference would be 18.85
Answer:

Step-by-step explanation:

compare with that y=mx+c
where m=slope .
So after comparing we get m=
As the lines are perpendicular


therefore m2=
Now from the equation
this equation passing to the point (-5,5) with m=

Therefore equation is
