Question

If 11, -24, 32, and -9 are the coordinates of the points M, N, P, and Q on a number line, then which of these segments is the longest?

MN, MP, NP, PQ, NQ

Easy points!

Answer 1

NP

because it is the distance between the lowest number (-24) and the highest number (32)

Answer 2

MN=11+|-21|=32

MP=11+32=42

NP=|-24|+32=56

PQ=32+|-9|=41

NQ=|-24|-|-9|=15

NP is the longest

Answer 3

np

Answer 4

MP

Answer 5

np because -24 (N)  is the lowest number, and 32 (P) is the highest number, their distance would be the furthest from each other

Answer 6

If -24 is the lowest and 32 is the highest then it should be NP.

Answer 7

NP = OP - ON = 32 - (-24) = 56 is the longest segment.
