If it's a graph: Solutions are points of intersection
The same line means infinitely many solutions
Parallel lines = never intersects = no solution
1 point of intersection = 1 solution
If it's a system of equations:
If you get _*x = _(a number), 1 solution (divide by the coefficient, and get only 1 possible value)
If you get x = x, infinitely many solutions (x can be anything and still equal itself)
If you get two different constants equaling (such as 1 = 2), there is no solution because no value of x can make those two values equal.

Answer:
A. 0 = −(x−6)^2+12
Step-by-step explanation:
The vertex form of a quadratic equation is ...
y = a(x -h)² +k . . . . . . for vertex (h, k) and scale factor 'a'
When the given vertex (h, k) = (6, 12) is used, we find the form of the equation to be ...
y = a(x -6)² +12
The ball will be on the ground when y = 0. Here, the vertical scale factor 'a' is -1, so the equation representing the ball being on the ground is ...
0 = -(x -6)² +12 . . . . . . matches choice A
