Answer:
the third option
Step-by-step explanation:
Our equation is
Equation of a vertical parabola is
where (h,k) is the center
The focus is
(h+p, k)
Equation of directrix is
x= h-p,
Here the center is (10,0)
Next, we factor out 4 in the original equation
So we have
So our p=9,
So our focus is
(10+9,0) or (19,0)
The third option is the answer

Answer:
m = -3
Step-by-step explanation:
Slope Formula:
Simply plug in our coordinates to find slope:
m = (11 - 2)/(5 - 8)
m = 9/-3
m = -3
