Answer:
Now, as you might recall, two lines are parallel when they are always the same distance apart and never intersect. y= -8 is parallel to y=3 and it passes through the point (-2, -8). The equation of this line is y= -8.

Answer:
![y=x^{2}+3](https://tex.z-dn.net/?f=y%3Dx%5E%7B2%7D%2B3)
Step-by-step explanation:
we know that
The equation of a vertical parabola in vertex form is equal to
![y=a(x-h)^{2}+k](https://tex.z-dn.net/?f=y%3Da%28x-h%29%5E%7B2%7D%2Bk)
where
(h,k) is the vertex
In this problem we have the vertex at point (0,3)
substitute
![y=a(x-0)^{2}+3](https://tex.z-dn.net/?f=y%3Da%28x-0%29%5E%7B2%7D%2B3)
![y=ax^{2}+3](https://tex.z-dn.net/?f=y%3Dax%5E%7B2%7D%2B3)
therefore
The option
is the answer
In this case the coefficient a is equal to 1
