Find the length of the segment AB by the formula for the distance between the points: a) A (4), B (-6). b) A (-32), B (-28) c) A (-8), B (4). d) A (-101), B (-34).

The distance between two points lying on the coordinate line is the length of the segment that connects them. To find the length of such a segment, it is necessary to subtract the coordinate of the left end from the coordinates of the right end.

L = x (n) – x (l).

a) Coordinate of the right end (4), left (-6).

L = 4 – (-6) = 4 + 6 = 10.

b) Coordinate of the right end (-28), left (-32).

L = (-28) – (-32) = -28 + 32 = 4.

c) Coordinate of the right end (4), left (-8).

L = 4 – (-8) = 4 + 8 = 12.

d) Coordinate of the right end (-34), left (-101).

L = -34 – (-101) = -34 + 101 = 67.

Answer 10, 4, 12, 67.
