A horizontal directrix means a vertical parabola. (y value of focus) — (y value of directrix) 2 _ h = the x-coordinate ofthe focus = 3 Solve for k: The y-value ofthe focus is k + p, so k+1—2 Write

Use the equation for a horizontal parabola, y 2 = 4px, and replace p with the x coordinate of the focus: y 2 = 4 (-8)x Simplify: y 2 = -32x Plot the focus and directrix and sketch the parabola. B
