<span>Its standard form of equation: (x-h)^2=-4p (y-k), (h,k)=(x,y) coordinates of the vertex
</span><span>For given parabola: Vertex = (-8, 2)
(x-(-8))</span>² = -4p(y - 2)
<span>solve for 4p using coordinates of given point ( -7, -1)
-7+8 = 4p (-1 - 2)
1 = 4p(-3)
4p = -1/3
So, Equation of given parabola:
(x+8)</span>² = -(y-2) / 3
Hope this helps!
Answer:
the answer is b
Step-by-step explanation:

Alright, here it is
w=(q+p)/(q-pq)
factor out the q in the bottom part
w=(q+p)/[(q)(1-p)]
multiply both sides by q
wq=(q+p)/(1-p)
add 1 to both sides, but add (1-p)/(1-p) to the right side since that equals 1
wq+1=(q+1+p-p)/(1-p)=(q+1)/(1-p)
multiply both sdies by (1-p)
(wq+1)(1-p)=q+1
divide both sdies by (wq+1)
1-p=(q+1)/(wq+1)
subtract 1 from both sdies
-p=[(q+1)/(wq+1)]-1
multiply by -1
p=-[(q+1)/(wq+1)]+1 or
Point slope form:
we need a point (x₀,y₀) and the slope (m).
y-y₀=m(x-x₀)
In this case:
m=3
(5,19)
y-19=3(x-5)
y-19=3x-15
y=3x-15+19
y=3x+4
Answer: y=3x+4
