Percentage growth is a measure of how rapidly a value is increasing or decreasing relative to its original value. It tells us how much the value changes compared to the baseline value rather than directly comparing it to other values.
Formally, the percentage growth can be expressed as:
(New value - Old value) / Old value * 100%
For example, let's say we have two points on a line graph:
Point A: (x,y) = (5, 10)
Point B: (x,y) = (10, 20)
The percentage growth between these two points can be calculated as:
(20 - 10) / 10 * 100% = 50%
Therefore, the value increased by 50% between point A and B.
Here's another way to think about it:
Imagine a line graph with point A at (0, 0) and point B at (100, 200). The percentage growth between these two points tells us that the value at B is 200, which is 50% more than the value at A.
Remember:
Percentage growth is always calculated relative to a baseline value.
It tells us the rate of increase or decrease rather than the absolute difference.
The result of calculating percentage growth is always a percentage.
By understanding and applying these concepts, you can easily find the percentage growth between two points on a line graph
