Question 80

Multiple Choice

The symmetric equations of the normal line to the surface 3z=x2+y223 z = x ^ { 2 } + y ^ { 2 } - 2 at (-2, -4, 6) are


A) x+24=y+48=z63\frac { x + 2 } { 4 } = \frac { y + 4 } { 8 } = \frac { z - 6 } { 3 }
B) x+24=y+48=z63\frac { x + 2 } { - 4 } = \frac { y + 4 } { 8 } = \frac { z - 6 } { 3 }
C) x+24=y+48=z63\frac { x + 2 } { 4 } = \frac { y + 4 } { - 8 } = \frac { z - 6 } { 3 }
D) x+24=y+48=z63\frac { x + 2 } { 4 } = \frac { y + 4 } { 8 } = \frac { z - 6 } { - 3 }
E) x+24=y+48=z63\frac { x + 2 } { - 4 } = \frac { y + 4 } { 8 } = \frac { z - 6 } { - 3 }
