Answer:
−25 is 25 units to the left of zero on a number line and
The opposite of −25 is 25 units to the right of zero on a number line.
Step-by-step explanation:
- a line on which we have numbers from negative infinity till positive infinity is a number line.
- so, it will obviously have 0 in the middle.
- in the left we will have negative numbers and on the right of 0 we will have positive numbers.
- the magnitude of the numbers will be increasing from 0 on both the sides.
- see the uploaded image in the attachment for better understanding.
- so, by seeing the image in attachment, we can say that,
−25 is 25 units to the left of zero on a number line and
The opposite of −25 is 25 units to the right of zero on a number line.
here, opposite of -25 refers to +25, which will be 25 units to the right of zero on a number line.
