About question number 58.
00:03
It's talking about what are the different points one must keep in mind while choosing a suitable scale for drawing a graph.
00:11
So first of whenever we draw a graph, we have two straight lines of perpendicular to each other.
00:17
One is the vertical line and one is the horizontal line and they intersect each other at a point which is called the origin.
00:25
So this would be marked as origin.
00:27
Now if you are choosing the scale, then they, that actually depends on the values which are given to us.
00:33
So let's say, for example, let's talk about two instances.
00:37
The first instance talks about both other distance versus time graphs.
00:42
So let's say the first instance talks about this is the distance and this is the time.
00:49
So the first instance talks about 100, 200, 300, and the time is 2, 4, 6 and 8.
00:58
So this is in meters and this is in second.
01:02
So if you want to plot this kind of graph, so we know that the units are 100, 200, 300, 400, so it's better to either mark as 50, 150, 100, and so on, or we can either mark it as one unit is equal to 100 meters.
01:18
So 100, 200, 300, 400, and so on.
01:22
And on the x -axis, we are going to mark one unit as one second, so one unit as two seconds.
01:27
It's going to be 2, 4, 6, and 8.
01:30
So 2, 4, 6, and 8 is going to be over here.
01:35
On the contrary, if we have a scaling, something like if we have the values, let's say, something like 20, 30, 60, 70, something like this.
01:52
And we have 1, 3, 7, and let's say 9.
01:57
So in this case, it won't be a good idea...
