(b) find an equation for C. Section 4: Sneaky Question 10. Prove that for all real values of k, the line with equation y = k - x intersects the curve with equation y = x2 + kx - 3 at two points.9. The points P (-3, 2), Q (9, 10) and R (a, 4) lie on the circle as shown. O(9, 10) R(a, 4) P(-3, 2) O X C Given that PR is a diameter of C, (a) show that a = 13
