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. Understand positive negative zero. The second derivative y 2 tells us that the change in this change is constant.
Which tells us the slope of the function at any time t.
Plug the x -value x 1 of the point into the derivative. Calculate the slope of a linear function. Find the number in front of the x usually written as m to determine slope. Plug the x -value x 1 of the point into the derivative.
