Answer: The axis of symmetry is x = 0
This is basically saying that the axis of symmetry is the vertical y axis

The vertex is either the highest point or the lowest point on the parabola, depending on what the value of 'a' is. If the vertex is the y intercept, then the vertex is on the y axis. The axis of symmetry goes through the vertex.

Alexxandr [17]

Answer:

\large\boxed{B.\ y-\dfrac{1}{3}=\dfrac{3}{4}(x-4)}

Step-by-step explanation:

The point-slope form of an equation:

y-y_1=m(x-x_1)

m - slope

We have

m=\dfrac{3}{4},\ \left(4,\ \dfrac{1}{3}\right)

Substitute:

y-\dfrac{1}{3}=\dfrac{3}{4}(x-4)
