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
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.
