Question

1. plot the points on the number line. 2.1, $-0.4$, 1.3, $-1.8$

Explanation:

Step1: Identify interval scale

Each major tick (-2, -1, 0, 1, 2) is split into 10 equal smaller ticks, so each small tick = $0.1$.

Step2: Locate -1.8 on line

-1.8 is 2 ticks right of -2: $-2 + 0.2 = -1.8$

Step3: Locate -0.4 on line

-0.4 is 6 ticks right of -1: $-1 + 0.6 = -0.4$

Step4: Locate 1.3 on line

1.3 is 3 ticks right of 1: $1 + 0.3 = 1.3$

Step5: Locate 2.1 on line

2.1 is 1 tick right of 2: $2 + 0.1 = 2.1$

Answer:

• -1.8: Position 2 small ticks to the right of -2
• -0.4: Position 6 small ticks to the right of -1
• 1.3: Position 3 small ticks to the right of 1
• 2.1: Position 1 small tick to the right of 2

(When plotting, mark each value at the corresponding tick mark on the provided number line.)
