Equation of a drawn line tangent to elliptic curve
How do you find the equation of a tangent line if you are not given at least the value of one of the coordinates of the intersection?
More specifically, this question
says find the slope of the shown tangent lines to the curve. But there is no indication if the lines are special lines (e.g., a max or a min). From the graph, I can estimate that the lines seem to occur at x=-1 and x=-2, but cannot really be sure, and the question does not state so. Am I missing something?

Re: Equation of a drawn line tangent to elliptic curve
I would use the (apparent) orthogonality of certain pairs of the tangent lines. In doing so, I get the pair:
