Question

Someone pls help! i’m confused since i’ve never done this problem before

Answer 1

Answer:

Step-by-step explanation:

The midpoint of the line is just the midpoint (average) of each pair of x, y, and z

2a ((-4 + 5)/2, (4 - 1)/2, (3 + 3)/2) = (0.5, 1.5, 3)

2b ((-5.1 + 1.4)/2, (-2 + 1.7)/2, (9 + 11)/2) = (-1.85, -0.15, 10)

The distance between points is the root of the sum of squares of the difference between each x, y, and z.

3a √((2 - 4)² + (3 - 3)² + (5 - 1)²) = √20 = 2√5

3b √((-3 - 2)² + (7 - 4)² + (2 - (-1))²) = √43
