Question

What is the length of segment GH?

On a coordinate plane, line G H has points (0, negative 3), (8, 1).

Answer 1

4sqrt(5)

Explanation:

Length² = (-3-1)² + (0-8)²

Length² = 16 + 64

Length² = 80

Length = 4sqrt(5)

sqrt: square root

Answer 2

4 sqrt(5)

8.94427191

Explanation:

We want to find the length ( or distance) between the two points

d = sqrt( (x2-x1)^2 + (y2-y1)^2)

= sqrt( (8-0)^2 + (1 - -3)^2)

= sqrt( (8)^2 + (4^2)

= sqrt( 64+16)

sqrt( 80)

sqrt(16) sqrt(5)

4 sqrt(5)
