Question 1 A)What formula do you use to find the x-coordinate of the vertex of a quadratic equation?(1 point) Responses m=y2−y1x2−x1m=y2−y1x2−x1m 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+by=mx+by is equal to m x plus b x=−b2ax=−b2ax is equal to negative b over 2 A x=2abx=2abx is equal to 2 A over b

1 answer

The formula to find the x-coordinate of the vertex of a quadratic equation in the standard form ax2+bx+c is:

x=b2a

So the correct response is:

x=b2a
