Question

What is the midpoint of A(2, –3, 1) and Z(–6, 3, 1)??

Answer 1

( -2 , 0 , 1 )

Explanation:

Using the `color(blue)" mid-point formula "`

given 2 points `(x_1,y_1,z_1)" and " (x_2,y_2,z_2)`

then the midpoint of these 2 points is :

`[ 1/2(x_1+x_2) , 1/2(y_1+y_2) , 1/2(z_1+z_2) ]`

For the points A(2,-3,1) and Z(-6,3,1) the mid-point is :

`[1/2(2-6) , 1/2(-3+3) , 1/2(1+1) ] = (-2 , 0 , 1)`
