Question

Which number line shows the solutions to n > 0? -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 -6-5-4-3-2-1 1 2 3 4 5 6 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6

Answer 1

To solve problems concerning number lines, you have to note the following;

- Greater than (>) is represented by a small circle (not shaded) with an arrow pointing to the right.

- less than (<) is represented by a small circle (not shaded) with an arrow pointing to the left.

- less than or equal to (=) is represented by a small circle ( shaded) with an arrow pointing to the left.

- greater than or equal to (>/=) is represented by a small circle ( shaded) with an arrow pointing to the right.

Using the above rule to solve the problem;

`n>0`

You need to first of all locate 0 on the number line.

Then since the sign between them is greater than (>), the according to the given rule, It will be represented by a small circle (not shaded) on 0 with an arrow pointing to the right.

So, we have;
