Take the equation and test the options. To help you get started, I'll test option A to see if it is a solution.
Directrix (directrix):
Test (-2,1) 2x – 4y = 6 Replace x in the equation by -2 and replace y by 1. Simplify the left side. If it equals 6, the the point is a solution. 2*(-2) – 4*(1) = -4 -4 = -8 which is not 6. The point (-2,1) is not a solution of the equation. Test option B. @lizette_macias11
