Complete Question:
On a number line, the coordinates of X, Y, Z, and W are −8, −5, 4, and 6, respectively. Find the lengths of the two segments below. Then tell whether they are congruent. [tex] \overline{XY} [/tex] and [tex] \overline{ZW} [/tex]
Answer:
[tex] \overline{XY} = 3 [/tex]
[tex] \overline{ZW} = 2 [/tex]
They are not congruent
Step-by-step explanation:
Length of segment XY:
Coordinate of X = -8
Coordinate of Y = -5
[tex] \overline{XY} [/tex] = |-8 -(-5)| = |-8 + 5| = 3
Length of ZW:
Coordinate of Z = 4
Coordinate of W = 6
[tex] \overline{ZW} [/tex] = |4 - 6| = 2
[tex] \overline{XY} [/tex] ≠ [tex] \overline{ZW} [/tex], therefore, they are not congruent.
