1. The problem statement, all variables and given/known data Find the line passing through the point (0,-18) and tangent to the curve y=x^3-2 at some point. 2. Relevant equations y=mx+b 3. The attempt at a solution Well, I know the derivative is 3x^2, and that should be the slope of the line at the point of tangency. I'm just not sure how to find out what point the curve shares with the line! I know that seems like a pretty bad attempt at a solution, I just need a hint about where to start with this one.
