ZC
za
Not drawn to scale.

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
