Question

Find the midpoint of the line joining the points (1,2,3) and (-2,4,2)

Answer 1

The midpoint is (-1/2, 3, 5/2)

Given

• the points (1,2,3) and (-2,4,2)

To find

• midpoint of the line joining the points

Solution

we are provided with two points that will make a line and are asked to find the midpoint of the line joining thes 2 ponts

given points (1,2,3) and (-2,4,2)

the midpoint of these points are given by (taking each co-ordinate separately)

x = (x1+x2)/2

or, x = (1-2)/2

or, x = -1/2

y = (y1+y2)/2

y = (2+4)/2

or, y = 6/2

or, y = 3

z = (z1+z2)/2

or, z = (3+2)/2

or, z = 5/2

Therefore, the midpoint is (-1/2, 3, 5/2)

Answer 2

Answer:

($\frac{-1}{2}$,3,$\frac{5}{2}$)

Step-by-step explanation:

Given:- Points (1,2,3)  and (-2,4,2).

To Find:- Midpoint of the given points.

Solution:-  

As we know, the formula to find the midpoint is:

                      = (co-ordinate of point1 + co-ordinate of point2) / 2

∴ x = $\frac{x1+x2}{2}$

     = $\frac{1+(-2)}{2}$

     = $\frac{-1}{2}$

⇒ y = $\frac{y1+y2}{2}$

      = $\frac{2+4}{2}$

      = 3

⇒ z = $\frac{z1+z2}{2}$

      = $\frac{3+2}{2}$

      = $\frac{5}{2}$
