Is this a d/dx thing? Just find y'(x), then set it equal to zero.
Or if ur not in calculus yet, use -2b/a. From ax^2+bx+c.
Do u have a specific parabola?
If you are using the distributive property you multiply the 8 on the outside to each inside number. This would leave you with 8a+32. Since there are no other numbers provided I believe that would be your answer.
Answer:
x = 4
Step-by-step explanation:
Note the x- coordinate of the 2 points are equal.
This indicates the line is vertical with equation
x = c
where c is the value of the x- coordinates the line passes through, that is 4
Thus the equation of the line is x = 4
