Respuesta :
We need to find the numbers those are 4 units far from 1.
If we go to 7 units left side of 1 on number line we would add -7 to 1, we get
1-7 = -6.
And if we go to 7 units right side of 1, we would add +7 on 1 to get the number.
1+7 =8.
First we would plot a number 1 on number line.
Then we would go 7 units on the left side of 1 on number line, we would get -6.
Now, we would go 7 units right of the right side of 1 on the number line, we would get 8.
