Final answer:
The length of the segment with endpoints (-7,1) and (1,3) is approximately 8.246 meters.
Step-by-step explanation:
To find the length of a segment with endpoints (-7,1) and (1,3), we can use the distance formula.
The distance formula states that the distance between two points (x1, y1) and (x2, y2) is given by √((x2 - x1)^2 + (y2 - y1)^2).
So, in this case, the distance is √((1 - (-7))^2 + (3 - 1)^2) = √(8^2 + 2^2) = √(64 + 4) = √68.
Therefore, the length of the segment is √68 or approximately 8.246 meters.
