Find the correct number line for the expression $-3-1.5$ .

STEP 1

Assumptions
1. We are working with real numbers on a number line.
2. The operation to perform is subtraction.
3. We are subtracting $1.5$ from $-3$ .

STEP 2

To find the result of $-3 - 1.5$ , we need to subtract $1.5$ from $-3$ .
$-3 - 1.5$

STEP 3

Since we are subtracting a positive number from a negative number, the result will be more negative.
$-3 - 1.5 = -3 + (-1.5)$

STEP 4

Add the two negative numbers together.
$-3 + (-1.5) = -4.5$

STEP 5

The result of $-3 - 1.5$ is $-4.5$ . This means on the number line, we start at $-3$ and move $1.5$ units to the left to reach $-4.5$ .
The correct number line will show the point $-4.5$ marked on it.
