Answer 1

a) The attached pictures show the line number and the plot of the numbers.

b) The opposite of a number is the same distance from zero in the opposite way.

The attached pictures show the number line with the three numbers and their respective opposites.

To find the opposite of a number, we need to find the number of places on the scale from zero. Then, we count the same number of places from zero in the opposite way.
