-6x-6=x²-5x-6
x²+x=0
x(x+1)=0
x=0, x=-1
x=0, y=-6x-6=-6*0-6=-6      (0,-6)
x=-1, y=-6x-6=-6*(-1)-6=0    (-1,0)

Answer (-1.0) and (0,-6) . The last one.

Check
(0,-6), y=-6-x,   -6=-6-0, -6=-6  True
y=x²-5x-6, -6=0+0-6,  -6=-6,  True
(-1,0),y=-6-x,   0=-6-(-6), 0=0  True
y=x²-5x-6,    0=1²-5(-1)-6=1+5-6=6-6=0,    0=0 True,

So,
Answer (-1.0) and (0,-6) . The last one.

Assuming you mean
\lim_{x \to 4} \frac{\sqrt{x+5}-3}{4-x}

that means as x approaches 4

if we sub 0 for x we get
0/0
and intermitent form
use l'hopital's rule

so
take the derivitive of the top and bottom seperatly
l'hopitals rule is something like
if \lim_{x \to n} \frac{f(x)}{g(x)} results in 0/0 or -∞/∞ or∞/∞ then keep doing it until f(n)/g(n) gives a form that isn't intermitent

so

take derivitive of top and bottom
\dfrac{\frac{1}{2\sqrt{x+5}}}{-1}
now, if we subsitute 4 for x we get
\dfrac{\frac{1}{2\sqrt{4+5}}}{-1}=

\dfrac{\frac{1}{2\sqrt{9}}}{-1}=

\dfrac{\frac{1}{2(3)}}{-1}=

\dfrac{\frac{1}{6}}{-1}=

\dfrac{1}{-6}=\dfrac{-1}{6}
