Coordinating The Intersection(s) (Posted on 2008-07-15) Difficulty: 3 of 5
The circle R is tangent to the line y= x, and its point of tangency is 5√2 from the origin, that is (0, 0). The length of the chord made by the line y = -x on R is 2√22 and (-12, 2) lies inside R.

At which coordinate(s) do the circle R intersect the parabola x = -y2?

The required points of intersection are:
(-2.53542, 1.59229), (-2.962934, -1.72132), (-17.69971, -4.2071), and:
(-18.80194, 4.33612).
