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 correct response from your options is:
x = −b/(2a)
What formula do you use to find the x-coordinate of the vertex of a quadratic equation?(1 point)

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
y is equal to m x plus b
x=−b2a
x is equal to negative b over 2 A
x=2ab
