Find the slope of the line at the point .

You are watching: Find the slope of the curve at the given point p and an equation of the tangent line at p    Explanation:

First find the slope of the tangent to the line by taking the derivative.

Using the Exponential Rule we get the following,  .

Then plug 1 into the equation as 1 is the point to find the slope at. .

Explanation:

One way of finding the slope at a given point is by finding the derivative. In this case, we can take the derivative of y with respect to x, and plug in the desired value for x. Using the exponential rule we get the following derivative, .

Plugging in x=2 from the point 2,3 gives us the final slope,   Thus our slope at the specific point is .

Note that in this case, using the y coordinate was not necessary.

Explanation:

To find the slope of the tangent line of the function at the given value, evaluate the first derivative for the given.

The first derivative is

and for this function and So the slope is Explanation:

To find the slope of the tangent line of the function at the given value, evaluate the first derivative for the given value.

The first derivative is

and for this function and plugging in the specific x value we get, So the slope is .

Explanation:

Calculate the derivative of by using the derivative rules. The derivative function determines the slope at any point of the original function.

The derivative is: With the given point  . Substitute this value to the derivative function to determine the slope at that point.
