Answer quick 25 actual points! find the standard form of the equation of the parabola with a vertex at the origin and a focus at (0, -7). (answer choices are in picture)

The vertex of the parabola is at (0,0), and the focus is at (0,-7). 

The focus is given by the following values:



h and k represent the x and y values of the vertex. We want to solve for p.

Set the y value for the focus equal to -7:



We know that k = 0, so we can simplify to get p by itself:



Standard form of a vertical parabola is given by the following formula:



Plug in all of your known values into the formula:






The answer is "y^2 = -28x".

Formula for parabola with focus at (0,p) and vertex at origin

Since focus is at (0,-7), p = -7 and

Iwould like to think so. what’s the question you need with?

This is what i found “answer: a rigid transformation preserves both the side lengths and the angle measures of a polygon. step-by-step explanation: rigid transformations are the transformations which does not affect the size and the shape of figure .” i hope this you for what your looking for. can you plz mark me brainliest?
