If the line, `ax+ by + c = 0` is a normal to the curve `xy =2`

If the line ax + by + c = 0 is a normal to the curve xy = 1 then

If the line ax + by + c = 0 is a normal to the curve xy = K^(2) then show that a and b have opposite signs.

If the line ax + by + c =0 is a normal to the curve xy+1=0 ,then 1) ab 2) ab=0 3) ab>0 d) ab=-3

If the line ax+by+c=0 is a normal to the curve xy=1 then

If the line ax+by+c=0 is a normal to the curve xy=1 , then :

If the line ax+by +c =0 is a normal to the curve xy=1 at the point (1, 1), then -

If the line ax + by + c = 0 is a tangent to the curve xy + 4 = 0 then

If the line ax+by+c=0 is normal to the curve xy+5=0 , then
