The vertex is exactly half way between directrix and focus. In this case the vertex is (8,-7)
(h,k)
P is the distance between the vertex and either the directrix or focus, in this case p = 1.
a = 1/(4p) or 1/(4*1) or 1/4
write the equation in vertex form
y = a(x-h)^2 + k
y = 1/4(x-8)^2 -7
Answer:
Y=4x+9
Step-by-step explanation:
Use rise over run to find 2 points for the slope. B is as simple as looking where the line passes y.
Hope this helps with the answer to your question:)
A. 6x-y=1 can go to 6x-y-1=0 and then 6x-1 = y
Its b !!!!!!!!!!!!!!!!!!!!!!!!!!!!!
