Iactually have 5 questions on the same thing, just different setups. but how would i go about solving them?
1. derive the equation of the parabola with a focus at (−5, −5) and a directrix of y = 7
2. derive the equation of the parabola with a focus at (6, 2) and a directrix of y = 1
3. derive the equation of the parabola with a focus at (−5, 5) and a directrix of y = -1.
4. derive the equation of the parabola with a focus at (0, −4) and a directrix of y = 4
5. derive the equation of the parabola with a focus at (−2, 4) and a directrix of y = 6. put the equation in standard form.
