Answer 1

To analyze Line 1 and Line 2, let's break down the sums and represent them with dots, as specified.

### Line 1
The expression in Line 1 is:
- 5 plus 4
- Written out as: 5 + 4

We can represent 5 and 4 with dots:
- 5 can be represented as: ●●●●●
- plus as: plus
- 4 can be represented as: ●●●●

If we represent the '+' with dots and commas then, to visualize this, we have:
- 5 dots + 4 dots = 5 dots + 4 dots

Counting the total number of dots:
- 5 (from 5) + 4 (from 4) = 9 dots

So, the answer for Line 1 is as follows:
- Line 1 says plus, which could be represented using dots as ●●●●● plus ●●●●, for a total of **9** dots.

### Line 2
The expression in Line 2 is:
- 4 plus 5
- Written out as: 4 + 5

We can represent 4 and 5 with dots as well:
- 4 can be represented as: ●●●●
- plus as: plus
- 5 can be represented as: ●●●●●

When counting the total number of dots:
- 4 (from 4) + 5 (from 5) = 9 dots.

So, the answer for Line 2 is as follows:
- Line 2 says plus, which could be represented using dots as ●●●● plus ●●●●●, for a total of **9** dots.

### Final Summary
- Line 1 representation: 5 dots and 4 dots = **9** dots.
- Line 2 representation: 4 dots and 5 dots = **9** dots.

So the answers to fill in the blanks would look like this:

The expression was rewritten using the **dot representation**.
Line 1 says plus, which could be represented using dots as ●●●●● plus ●●●●, for a total of **9** dots.
Line 2 says plus, which could be represented using dots as ●●●● plus ●●●●●, for a total of **9** dots.
