Question

1. 2, 6, -2, -1

Explanation:

Step1: Understand the Number Line

A number line has negative numbers to the left of 0 and positive numbers to the right. Each tick mark represents a unit (assuming equal spacing).

Step2: Locate -2

-2 is 2 units to the left of 0. Find the tick mark that is two units left of the 0 mark.

Step3: Locate -1

-1 is 1 unit to the left of 0, so it's one tick mark to the right of -2 (or one unit left of 0).

Step4: Locate 2

2 is 2 units to the right of 0. Find the tick mark two units right of 0.

Step5: Locate 6

6 is 6 units to the right of 0. Since the number line shown has several tick marks, we count 6 units from 0 (or from 2, we can count 4 more units to reach 6).

To plot the numbers:

• Mark -2 at the appropriate left - side tick.
• Mark -1 at the tick between -2 and 0.
• Mark 2 at the tick two units right of 0.
• Mark 6 at the tick six units right of 0 (or count from 2: 2, 3, 4, 5, 6 - so four more ticks from 2).

Answer:

The numbers 2, 6, -2, -1 are plotted on the number line with -2 and -1 on the left of 0 (with -2 further left than -1) and 2 and 6 on the right of 0 (with 6 further right than 2).
