Question

tangent line equation of f(x)=x+x/3

Answer 1

\[f(x) = x+\frac{ 1 }{ 3 }x\]
Add.
\[f(x) = \frac{ 4 }{ 3 }x\]
Now differentiate.
That's your slope. Without a specific point, it's just y=mx+b where m is the answer you got for the derivative.

Answer 2

I have the specific point of (-3,-4)

Answer 3

Thank you!
