Find equations for $(a)$ the tangent plane and $($ b $)$ the normal line at the poiet $P,(1,1,1)$ on the uripre $x^{2}4y^{2}3c^2=8.$

$($a$)$ Which equation describes the largent plane?

A$.x4y3z=1$

B$.5x4y3z=12$

C$.-84y5r=8$

D$.x5y3z=9$

fil, Setert the nequations for the nornal be

A$.x=16$

$x=21$

$y=41$

$z=61$

$y=1-6$

$2=42$

C$.x=1-2x$

D$.x=12t$
