Question

Can someone help me! Please show pictures of the number line thank you!

Answer 1

First, we have to make
`w` the subject of the equation:

`w - 0.9 > -2.1\\w > -2.1 + 0.9\\w > -1.2`

This shows that
`w` is less than but not equal to
`-1.2`. So we are going to use an arrow that has a non-shaded circle. Since the symbol is the greater than symbol, or >, the arrow will point to the right. Thus, the arrow we choose will be the last arrow.

Now since we are comparing
`w` with
`-1.2`, we place the arrow above the
`-1.2` point. That's how he place the arrow in the number line.

Answer 2

The graph is an open circle at -1 with the line going towards the positive numbers.
