Question 3 (d)

Represent the following number on a number line:
–1

Answer 1

To represent -1 on the number line, we will follow the steps as follows:

• Draw a line and mark some points at equal distance on it as shown in the figure.
• Mark a point as zero on it.
• Points to the right of zero are positive integers and are marked 1, 2, 3, etc.
• Points to the left of zero are negative integers and are marked – 1, – 2, – 3 etc.
• In order to mark -1 on this line, we move 1 point to the left of zero.
