Hello everyone

I am studying tangents and come across this kind of problem where I am going to find the equation for one or more tangent with a specific directioncoefficient for an function.

Example:

**Find the tangents for the funtion that has an directioncoefficient of 4.**
How do I solve this kind of problem? I am halfway through, I think.

First we get the derivate for the function, which is:

The we check and see for what X value Y equals 4, correct?

And after that? Assuming that the above is correct.
