Hello there. I am kind of confused about this and have no idea where to start.(adsbygoogle = window.adsbygoogle || []).push({});

FOr example:

If the line given is y=x^2+4x-1 and we are to find the slope of the tangent of the perpendicular line which passes through x-coordinate -3.

Where do I start?
