Answer: -2/7
This value is a fraction.
----------------------------------
Work Shown:
The first two rows in the table produce these two points (x1,y1) = (-14,8) and (x2,y2) = (-7,6)
So, x1=-14, y1=8, x2=-7, and y2=6
Plug these four values into the slope formula and simplify
m = (y2 - y1)/(x2 - x1)
m = (6 - 8)/(-7 - (-14))
m = (6 - 8)/(-7 + 14)
m = -2/7
Answer:
B) 10
Step-by-step explanation:
|5-15|
Do what is inside the absolute values signs
5-15
-10
|-10|
Absolute value means always positive so take the positive value of -10
10
The equation of the directrix of the parabola given is x = 6, Option D is the correct answer.
<h3>What is Directrix of a Parabola ?</h3>
A parabola is a U shaped curve whose all point are at same distnace from a point called as focus and a line called as Directrix .
The equation of the parabola given is
y² = -24x
When the standard equation of parabola is
(y - k)² = 4p (x - h),
where the focus is (h + p, k) and the directrix is x = h - p.
here h = 0
p = -24/4 = -6
x = 0 - (-6)
x = 6
Therefore Option D is the correct answer.
