Answer:
(-1,-2)
Step-by-step explanation:
Let's bring back to memory vertex formula for parabolas.
Where (h,k) is the vertex.
In 
The vertex is (-1,-2)
( 1 ,2) is in first quadrant
(-1,2) is in second
(-1,-2) is in the third
( 1, -2) is in 4th quadrant
Two equations with infinite solutions would look the exact same. Example:
y=mx+b
y=mx+b
Example 2
y=2x+5
y=2x+5
For an equation with no solution they would have the same slope but different y intercepts. An equation with same slope and same y intercepts would have infinite solutions.
Hello there,
<span>Which of these is a common characteristic of cnidarians?
</span>All Cnidarians<span> have tentacles with stinging cells in their tips which are used to capture and subdue prey.
