The Gradient Function I am trying to find a formula that will work out the gradient of any line (the gradient function) I am going to start with the most simple cases, e.g. y=x, y=x², y=x³ etc. They are probably going to be the easiest equations to solve as they are likely to be less complex, and hopefully the formulas to the more complex equations will be easier to discover by looking at these first formulas. I am going to look at the line y=x² first. y=x² x 1 2 3 4 y 1 4 9 16 Please refer to graph on separate piece of paper One of the most obvious things I notice is that as the co-ordinates increase so does the gradient. Not only can you see that from the results below, but also on the graph you can see that the line gets steeper and steeper. This makes sense, as the higher the number x is the larger the difference...
