Answer:
The vertex would be (-3, -1)
Step-by-step explanation:
Since this is in vertex form already, a(x-h)^2+k where h is the x value of the vetex, and k is y.
We would take the opposite of +3 and get -3, which gives us our x cordinate.
We don't change the k value, so it just stays -1, giving us our y value.
Therefore, the vertex is at (-3, -1)
Hope this helps!

Method of elimination or reduction
Adding two equations is to obtain a new equation whose right (left) member is the sum of the right (left) members of the equations that are added together.
<span> 7X+5y=19
-7X-2y=-16.
</span> Adding two equations
3y=3 ---> y=1
then
7x+5(1)=19
7x=19-5
x=14/7=2
