Tools≻Load Package: Student Calculus 1

Control-drag $f\left(x\right)\=\dots$ 
Context Panel: Assign Function

Type $f\left(x\right)$
Context Panel: Tutors≻Taylor Approximation

Set Degree = 1

Set $x\=3$ 

Figure 3.3.4(a) is an image of the Taylor Approximation tutor in which $P_1\left(x\right)$, the Taylor polynomial of degree 1, determines the equation of the tangent line in the form $y\=P_1\left(x\right)$.

The  tutor will appear with $x\=3$ and the Degree set to the default 4.

Using the point-slope form, type the equation of the tangent line.
