draw a perpendicular line from the directrix passing through the focus, this will be the line of symmetry.
The vertex(h, k) will be located on the line half way between the focus and directrix.
The distance from the focus to the vertex is called the focal length, call it a. The then equation is
(x - h)^2 = 4a(y - k)
the equation can be manipulated to
y = 1/4a(x - h)^2 + k
hope it helps
Answer:
Step-by-step explanation:
The slope is going to be the one that has the X by it so your slope is going to be 5x. Then your y intercept is going to be the number behind the slope so the y intercept is positive 1.
The answer is "N". Even though "W" has parallel lines, "N" only has 2.
Hope it helps!
