Identify whether the given line is horizontal, vertical, or neither.

In this question, we’re given a line. Here it is. Just looks like a normal straight line. But we’re asked to identify something about this line. Is it horizontal? Is it vertical? Or is it neither of them? In other words, is it not horizontal or vertical? To answer the question correctly, we need to really understand what the words horizontal and vertical mean. Let’s remind ourselves.

If a line is horizontal, it’s perfectly level from left to right and doesn’t slope up or down at all. If our line was horizontal, we’d expected it to look like this. Now, if we look at the line we’re given, we can see that it does slope. If this was a road and we had to cycle along it, it would be really hard, a lot different than if the road surface was horizontal. This line is slanted or sloped. So, we know it’s not horizontal.

But is it vertical? What do we remember about vertical lines? A vertical line is perfectly straight up and down, going from top to bottom without leaning to the left or to the right. If our line was vertical, we’d expect it to look like this. But if we look at the line that we’re given, we can see that it doesn’t go straight up and down at all. If our line was the wall of a house, it would really be leaning to the side. This line is not vertical.

We’ve used our knowledge of horizontal and vertical lines to look at this line and say it’s not horizontal or vertical; it’s neither.
