Question

Which numbers are 9 units from −5 on this number line? Drag and drop all of the numbers that are 9 units from −5 to their correct position on the number line.

Answer 1

- 14 and + 4

consider 9 units left or right of - 5

- 5 - 9 = - 14 ( left of - 5 on the number line )

-5 + 9 = + 4 ( right of - 5 on the number line )

Answer 2

If you want to find the numbers that are 9 units away from -5, the thing you need to do is first, locate the -5 in the number line.

Now, move 9 units to the left, the number in where you landed, is 9 units away from -5

Now, go again to the -5, and now move 9 units to the right, the number where you landed is also 9 units away from -5.

In a regular number line, where the units are of a value of 1, these two numbers will be:

Left: -5 - 9 = -14,

Right -5 + 9 = 4
