Multiply both sides of the equation by 28 4y+7=10
Then move constants to the right side and change its sign 4y=10-7
Now subtract the numbers 4y=3 divide both sides by 4 so your answer is y=3/4

Derive the equation of the parabola with a focus at (0, −4) and a directrix of y = 4.

Goshia [24]

$\sqrt{(x_{0} - 0)^{2} + (y_{0} - (-4))^{2}} = |y_{0} - 4|$
<span> $\sqrt{(x_{0} - 0)^{2} + (y_{0} + 4)^{2}} = |y_{0} - 4|$
</span> $(x_{0} - 0)^{2} + (y_{0} + 4)^{2} = (y_{0} - 4)^{2}$
$(x_{0})^{2} + (y_{0} + 4)^{2} = (y_{0} - 4)^{2}$
$x_{0}^{2} + (y_{0}^{2} + 4y_{0} + 4y_{0} + 16) = y_{0}^{2} - 4y_{0} - 4y_{0} + 16$
$x_{0}^{2} + (y_{0}^{2} + 8y_{0} + 16) = y_{0}^{2} - 8y_{0} + 16$
$x_{0}^{2} + y_{0}^{2} + 8y_{0} + 16 = y_{0}^{2} - 8y_{0} + 16$
$x_{0}^{2} + 16y_{0} = 0$
$16y_{0} = -x_{0}^{2}$
$\frac{16y_{0}}{16} = \frac{-x_{0}^{2}}{16}$
$y_{0} = -\frac{1}{16}x_{0}^{2}$
$y = -\frac{1}{16}x^{2}$

The answer is C.
