Answer:
B
Step-by-step explanation:
You can use the key features (such as the vertex) to determine which is the correct equation
Answer:



Step-by-step explanation:
The given equation is 
We substitute the ordered pairs to see which ones satisfies the equation.
For (-1,-8), we put x=-1 and y=-8 to get:


This is not true.
For
we put x=-1 and
to get

This is true
For (3,3/2) we have 2(3)+6(3/2)=15
This implies 6+9=15
15=15
This is also True
For (-5,25/6), we have 2(-5)+6(25/6)=-10+25=15
This is also true.
