Question
What formula do you use to find the x-coordinate of the vertex of a quadratic equation?(1 point)
Responses
x=2ab
x is equal to 2 A over b
x=−b2a
x is equal to negative b over 2 A
m=y2−y1x2−x1
m is equal to the fraction with numerator y sub 2 minus y sub 1 and denominator x sub 2 minus x sub 1
y=mx+b

The correct formula to find the x-coordinate of the vertex of a quadratic equation in the form \( ax^2 + bx + c \) is:
\[ x = -\frac{b}{2a} \]
So, the response is:
**x is equal to negative b over 2 A.**
\[ x = -\frac{b}{2a} \]
So, the response is:
**x is equal to negative b over 2 A.**
