Question

Explain two ways you can use a number line to order the integers –3, +1, and –10.

Answer 1

-10,-3,1

1,-3,-10

Explanation:

We are given that integers are -3,+1 and -10

We have to explain two ways in which we can use a number line to order the given integers.

The two ways are

1.Arrange in increasing order:From least to greatest

2.Arrange in decreasing order: From greatest to least

We know that when we go left side of zero on a number line then the value decreases and when we go right side of zero then the value increases.

1.-10 is smallest integer in the given integers and 1 is a largest integer.

Therefore, -10,-3,1.

2.In decreasing order

1,-3,-10

Answer 2

From least to greatest: -10, -3, +1. From greatest to least: +1, -3, -10.
1st way: Just look at it.
2nd way: See which numbers are to the left of 0 on the number line. Those are your smaller (negative) numbers. The numbers that are on the right side of 0 are your bigger (positive) numbers.
