If y is proportional to x, we can draw a graph that shows the relationship. The shape of the graph will depend on the power and the constant of proportionality.
Here are some graphs that you should be able to recognise
This equation gives us a straight line. The gradient of the line is k.
This equation gives us a curve. The larger the value of k, the steeper the graph.
You have similar shaped curves for any powers between 0 and 1. Again, increasing k will make the graph steeper.
