Answer:
The vertex form of the equation is 
.
Step-by-step explanation:
You will use the equation 
to solve this parabola. (h, k) is the vertex. So, we plug this into the equation to get 
.
Then, we substitute the point as our x and y to get 
(a lot of simplifying was done here). Then, add 2 to the right side of the equation and isolate the 
to get 
. Finally, divide by 9 on both sides to get 
.
Now, substitute your 
back into the equation to get y = 
.
This is in vertex form. If the answer is needed in standard form, simply distribute and simplify to get 
.

Answer:
15 different swing sets
Step-by-step explanation:
The swing set is composed by one swing and one slide.
There is 5 different types of swing, so there are 5 possibilities to fill the one swing we need.
There are 3 different types of slides, so there are 3 possibilities to fill the one slide we need.
So, to find the total number of swing sets, we just need to multiply the swing possibilities and the slide possibilities:
Number of sets = 5 * 3 = 15 different sets
