If the x is squared, the parabola is vertical (opens up or down). If the y is squared, it is horizontal (opens left or right). If a is positive, the parabola opens up or to the right. If it is negative, it opens down or to the left.
The formula is x1+x2 divided by 2 and y1+y2 divided by 2.I hope this is what you where looking for
1. is the third choice
2. is second choice
