Solution

The length of the line segment AB can be calculated using the distance formula derived from the Pythagorean theorem. The distance d between two points A(x1, y1) and B(x2, y2) is given by:

d = sqrt[(x2-x1)² + (y2-y1)²]

Here, A = (0, 0) and B = (8, 2). So, x1 = 0, y1 = 0, x2 = 8, and y2 = 2.

Substituting these values into the distance formula gives:

d = sqrt[(8-0)² + (2-0)²] = sqrt[(8)² + (2)²] = sqrt[64 + 4] = sqrt[68] = 8.246 (rounded to three decimal places)

So, the length of the line segment AB is approximately 8.25 units. The correct answer is B. 8.25 units.
