### Example Question #1 : Number Lines

Plot the fraction on the number line.

**Possible Answers:**

**Correct answer:**

The fraction is less than and greater than , so it must fall between those points on the number line. Negative numbers are to the left of while positive numbers are to the right.

Because is less than , the point must be closer to than .

### Example Question #1 : Number Lines

Find the inequality that corresponds to the following number line.

**Possible Answers:**

**Correct answer:**

When looking at the number line, we can see that *x* is any integer between 2 and 7.

Anything to the right of an integer is considered "greater than" and anything left of an integer is considered "less than".

So, we know that *x* is greater than 2, but less than 7.

Now, since the circle above the 2 is shaded in, 2 is included in the solution. The circle above the 7 is not shaded in, so 7 is not included in the solution.

We now know that *x *is greater than or equal to 2, and it is still less than 7.

Using the statement above, we will create 2 inequalities.

Now, can also be written as . It has the same value, it just looks a little different.

So we have the two inequalities

and

We can combine them, and it'll look like this

### Example Question #1 : Number Lines

Put in order from least to greatest.

**Possible Answers:**

**Correct answer:**

Thus, in increasing order:

### Example Question #1 : Number Lines

Find the inequality that corresponds with this number line.

**Possible Answers:**

**Correct answer:**

When looking at the number line,

we see at -5 there is a filled in circle. We also see there is an arrow going to the right of -5. Every integer to the right of -5 is greater than -5 itself. Because the circle above -5 is filled in, we know -5 is included in the inequality. We get
