Find the slope of a tangent line using limits

Full solution

Q. Find the slope of the tangent line to

k(x) = x

at

x = 2

.

\newline

Write your answer as an integer or a fraction. Simplify any fractions.

\newline

____

Identify function and point: Identify the function and the point where the slope is needed. $\newline$ Function: $k(x) = x$ $\newline$ Point: $x = 2$
Determine derivative of function: Determine the derivative of $k(x)$ to find the slope of the tangent line. $\newline$ Derivative of $k(x) = 1$ (since the derivative of $x$ with respect to $x$ is $1$ )
Evaluate derivative at point: Evaluate the derivative at $x = 2$ to find the slope at that point. $\newline$ Slope at $x = 2$ = $1$
