Question

Which product is modeled by the number line below?

Answer 1

Answer:

The correct option is 2.

Step-by-step explanation:

From the given number line it is clear that there are 4 jumps of 2 units in opposite direction.

After first jump, the total covered distance is

$-(2)\times (1)=-2$

After second jump, the total covered distance is

$-(2)\times (2)=-4$

After third jump, the total covered distance is

$-(2)\times (3)=-6$

After fourth jump, the total covered distance is

$-(2)\times (4)=-8$

It means the product (-2)(4) is modeled by the given number line.

Therefore the correct option is 2.

Answer 2

Proportion logic: 4/x = 5/1
