how to find the slope of an equation using derivative. We used these Derivative Rules. The following figure contains a sample function.

We can do this by filling in the point to get. The real derivative is obtained from the instantaneus rate of change in y with respect of x or the slope of the tangent line at that point. Which tells us the slope of the function at any time t.
Now that we know the slope of the line we can also find the entire formula of the line.
To do this you visualize a function of two variables z fx y as a surface floating over the xy-plane of a 3-D Cartesian graph. In order to find the slope of the given function y at x2 all we need to do is plug 2 into the derivative of y. Therefore the slope of our line would simply be y2322416 And because of this we also know the slope of our tangent line will be m16 So we know this will guarantee that our tangent line has the right slope now we just need to make sure it goes through the right point. Or when x5 the slope is 2x 10 and so on.
