A parabola can be drawn given a focus of (-6,3) and a directrix of x = -4. Write
elena55 [62]

Answer:

(y-3)^2=-4(x+5)

Step-by-step explanation:

Given the directrix is vertical, the parabola must have a horizontal axis since it's perpendicular to the directrix.

Therefore, we can use the form (y-k)^2=4p(x-h) where the focus is (h+p,k) and the directrix is x=h-p.

Therefore:

h+p=-6

h-p=-4

2h=-10

h=-5

So:

x=h-p

-4=-5-p

1=-p

-1=p

This means that the parabola opens to the left since p. Remember that p describes the distance between the vertex and focus point.

We can tell that k=3 given the focus point

In conclusion, the equation of the parabola is (y-3)^2=-4(x+5)

Take a look at the figure. What are the coordinates of the point labeled A in the graph shown?
Misha Larkins [42]

Answer:

(2,-2)

Step-by-step explanation:

Point A is 2 units to the right of the origin so the x coordinate is 2

It is also 2 units down so the y coordinate is -2

The point is (x,y) so A = (2,-2)
