Question 4 (a)

Adjacent figure is a vertical number line, representing integers. Observe it and locate the following point:

If point D is +8 then which point is –8?

Answer 1

As per the question, point D represents +8 on the vertical number line.

Point D is 8 points above 0.
Hence all points above 0 are positive integers and all points below 0 are negative integers.

We have to find which point represents -8.

-8 is 8 points less than 0.

Point F is 8 points less than 0.

Hence, F represents -8.
