A parabola has a focus of F(-6,6) and a directrix of I = -8. P(x, y) represents any point on the parabola, while D(-8, y) represents any point on the directrix.
The following is Marcel's work.
Step 1: FP = DP
Step 2: (-(-6))2 + (y – 6)2 = V(r-(-8))2 + (y – y)2
Step 3: x2 + 12x +36 + y2 – 12y + 36 = 22 + 163 +64
Step 4: y2 - 12y + 8 = 40
Step 5: -y– 3y + 2 = 1
