slope is what is infront of x and y intercept is the number after the slope
Given t = time and h = height

From the equation.

h is the axis od symmetry
(h, k) is the vertex.
In the equation, h is 1 and k is 16.
So the maximum value is 16 at t = 1.
The ball reaches maximum at 16 and it takes t = 1 to reach the maximum point.
