Write the equation for a parabola with a focus at (-3,-5) and a directrix at x=-7x=
1 answer:
Answer:
Recall that the parabola
y^2 = 4px
has its
focus at (p,0)
directrix at x = -p
vertex is midway between the focus and the directrix, at (-5,-5)
So, here we clearly have p = 2
So the equations is
(y+5)^2 = 8(x+5)^2

Answer:
-2
Step-by-step explanation:
We can find the slope of a line given two points from
m = (y2-y1)/(x2-x1)
= (-2-4)/(1--2)
= (-6)/(1+2)
=-6/3
=-2
