[SOLVED] Integration (Related to Physics)

This shouldn't take long

I have been given the general equation for a straight line which is:

y=mx+c

Now I know that to determine the gradient I can use:

m=\frac{y}{x}

Here is my question. Can I differentiate the initial equation given to get to m=\frac{y}{x}

If so, which I am sure you can, then I seem to have come across a problem, though I think it is a problem in my differentiation.

y=mx=c

\frac{dy}{dx}=mx^{-1}

m=\frac{y}{x^{-1}}

or

m=\frac{x}{y}

This does not agree with my initial statement. Either my differentiation is incorrect or I need to touch up on my laws of indices, and if neither of these maybe I am deluded and this can't be done anyway

(1) The slope is given by m = \Delta y / \Delta x, not m = y/x.
(2) The derivative (with respect to x) of mx + c is just m.

Just noticed the thread title is integration not differentiation. Thank you for your help.
