Question

points a(1,2,3) and b(-1,0,6)

a. find the midpoint of line segment AB
b. find the length of line segment AB

Answer 1

a(1,2,3) and b(-1,0,6)
\[\Huge M(\frac{1+(-1)}{2},\frac{2+0}{2},\frac{3+6}{2})\]

Answer 2

so it's 0, 1, 9/2?

Answer 3

yes

Answer 4

is the formula ( x1 + y1 / 2 , x2+y2 /2, x3+y3/2? :o

Answer 5

\[\Huge M(\frac{x+x_1}{2},\frac{y+y_1}{2},\frac{z+z_1}{2})\]

Answer 6

do you know how to find the length?

Answer 7

\[L=\sqrt{(x-x_1)^2+(y-y_1)^2+(z-z_1)^2}\]

Answer 8

\[L=\sqrt{17}\]

Answer 9

ahhhh okay!
thank you!!!
