Which is the directrix of a parabola with equation X^2=8y

1 answer:

4 0

Alright so, After rewriting the equation in a standard parabola, you get:
4 x 2 (y-0) =(x - 0)^2

Simplify it to get:
y= 0-p
y= 0-2

When you simplify that, your answer is:
y=-2

There you go folks, just saved you from reading that long paragraph of an answer the other guy has (I don't even think the answer is in there lol, I think he just wanted to help people solve it but still most people come here for answers)

Write the common rule to describe the translation using coordinate notation.

UNO [17]

The common rule is (x - 1, y + 3) can be used to describe the translation.

Step-by-step explanation:

Step 1:

The point J (-3, -4) becomes $J^{1}$ (-4, -1).

In order to write the rule for translation from J to $J^{1}$ , we subtract the x coordinate of J from $J^{1}$ and subtract the y coordinate of J from $J^{1}$ .

The x coordinate $= -4-(-3) = -4+3 = -1.$
