Question

model -0.2 + (-1.3) on the number line. -2 -1.9 -1.8 -1.7 -1.6 -1.5 -1.4 -1.3 -1.2 -1.1 -1 -0.9 -0.8 -0.7 -0.6 -0.5 -0.4 -0.3 -0.2 -0.1 0

Explanation:

Step1: Start at -0.2

Locate -0.2 on the number line. This is the initial point for the addition.

Step2: Move left 1.3 units

Since we are adding -1.3, we move 1.3 units to the left from -0.2. Moving left on the number line represents adding a negative number.
-0.2 + (-1.3) = -1.5. So we end at -1.5.

Answer:

To model \(-0.2 + (-1.3)\) on the number line:

1. Start at \(-0.2\).
2. Move 1.3 units to the left (because we add \(-1.3\)). This lands at \(-1.5\) (since \(-0.2 - 1.3 = -1.5\)). The final point is at \(-1.5\) on the number line.
