Line segment XY has the coordinates X(–12, –6) and Y(5, 6). What is the approximate length of line segment XY? A.
21.1 units

B.
20.8 units

C.
13.9 units

D.
12.5 units

The approximate length of line segment XY is 20.8 units

Distance between two points

The formula for calculating the distance between two points is expressed as:

A = √(x2-x1)²+(y2-y1)²

Given the coordinate points X(–12, –6) and Y(5, 6). The distance between them is expressed as;

XY = √(5+12)²+(6+6)²

XY = √(17)²+(12)²

XY = √269 + 144

XY = 20.8

Hence the approximate length of line segment XY is 20.8 units
