Question

c) which of the following expressions matches this number line?
options: -5 + 10, -3 × (-3), 3 · (-3), -10 + (-5), 10 ÷ (-2)

Explanation:

Step1: Find number line's result

The number line starts at 0, moves right 5, then right another 5, then left 15.
$0 + 5 + 5 - 15 = -5$

Step2: Calculate each option

Option1: $-5 + 10 = 5$

Option2: $-3 \times (-3) = 9$

Option3: $3 \cdot (-3) = -9$

Option4: $-10 + (-5) = -15$

Option5: $10 \div (-2) = -5$

Step3: Match result to option

The number line result is -5, which matches $10 \div (-2)$.

Answer:

$10 \div (-2)$
