Miki is trying to help her younger brother understand why 12−(−5) is equal to 17. She draws a number line to help. Explain how a number line could help to show that 12−(−5) is equal to 17. (1 point)

Starting at 12 on the number line, you must move 5 units in the negative direction to get to 7.
Starting at 12 on the number line, you must move 5 units in the negative direction to get to 7.
Starting at −5 on the number line, you must move 17 units in the positive direction to get to 12.
Starting at negative 5 on the number line, you must move 17 units in the positive direction to get to 12.
Starting at 12 on the number line, you must move 17 units in the negative direction to get to −5.
Starting at 12 on the number line, you must move 17 units in the negative direction to get to negative 5 .
Starting at −5 on a number line, you must move 12 units in the positive direction to get to 17.
Starting at -5 on a number line, you must move 12 units in the positive direction to get to 17.
Starting at -5 on a number line, you must move 12 units in the positive direction to get to 17. But remember, that's just in case you want to take the scenic route. Why not just order an Uber instead? It will get you to 17 way faster and you won't have to worry about counting units on a number line.
Starting at 12 on the number line, you must move 5 units in the negative direction to get to 7. Then, you subtract 7 from 12, which gives you the result of 5.
Starting at 12 on the number line, you must move 5 units in the negative direction to get to 7. Then, to find 12 - (-5), we need to subtract -5 from 7. Subtracting a negative number is the same as adding the positive version of the number, so we can rewrite this as 7 + 5, which equals 12. Therefore, 12 - (-5) is equal to 12.
To show this on a number line, you would start at the point 12 and move 5 units to the left, ending up at 7. This visually represents the subtraction of -5 from 12 and shows that the result is 7.
On the other hand, starting at -5 on the number line, you would need to move 17 units in the positive direction to get to 12. This shows that adding 17 to -5 gives you the result of 12.
While it is important to understand the concept of adding and subtracting negative numbers, using a number line can provide a visual representation that can help in understanding the arithmetic operation being performed.
