A line segment has end points at (3, -5) and (4, 1) What is its length? a. 9 units
b. 6.9 units
c. 9.2 units
d. 5 units

need an explanation if possible please.

6.08units

Step-by-step explanation:

The distance between two points of a line is expressed as;

D = √(y2-y1)²+(x2-x1)²

Given the coordinates  (3, -5) and (4, 1);

D = √(1+5)²+(4-3)²

D = √(6)²+(1)²

D = √36+1

D = √37

D = 6.08 units

Hence its length is 6.08units

x = 3 ± √(5+y)
