What are the distances from the point (x, y) to the focus of the parabola and the directrix?
Select two answers.
O distance to the directrix: |y + 6|
O distance to the focus: (T – 2)2 + (y+ 5)²
O distance to the focus: V(r + 4)² + (y – 2)²
O distance to the focus: (T – 2)2 + (y + 4)²
O distance to the directrix: |y – 6|
distance to the directrix: |x + 6||
