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

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

x=−b2a
x is equal to negative b over 2 A

y=mx+b
y is equal to m x plus b

Answer 1

The correct formula to find the x-coordinate of the vertex of a quadratic equation in the form \( ax^2 + bx + c \) is:

**x = -b / (2a)**

So the correct response from your options is:

**x is equal to negative b over 2 A**
