To find the length of segment DE, we can use the distance formula:
Distance = √((x2 - x1)^2 + (y2 - y1)^2)
Plugging in the coordinates, we get:
Distance = √((1 - (-2))^2 + (3 - 7)^2)
Distance = √(3^2 + (-4)^2)
Distance = √(9 + 16)
Distance = √25
Distance = 5
Therefore, the length of segment DE is 5 units.
C. 5 units
Distance = √((x2 - x1)^2 + (y2 - y1)^2)

Distance = 5
Therefore, the length of segment DE is 5 units.
