In which pair of integers is the first integer not on the left of the other on the number line?
(−1, 10)
(−3, −5)
(−5, −3)
(−6, 0)
On a number line, smaller numbers are on the left and bigger numbers are on the right.
For negative numbers, the number nearer to 0 is bigger.
Example:
(-3) is nearer to (0) than (-5).
So (-3 > -5).
If (-3 > -5), then (-3) is to the right of (-5).
In the pair (( -3, -5 )), the first number (-3) is not on the left of the second number (-5).
Therefore, the correct option is B.
