Answer:
Step-by-step explanation:
You need to know:
Vertex form = 
The vertex is at
(h, k)
<u>Need to know about perfect squares </u>
<u>Need to know how to complete the square.</u>
-----------------------------------------------------------------------------------------
<u>To convert
you need to complete the square on the equation.</u>
Complete the Square
Divide -2 by 2 and then square it.


Add the one to the parentheses and subtract the one from the 5
Square
Now we have
<u>Next add</u> -5 - 1 = -6
Our quadratic is in vertex form now.
Vertex form = 
our equation =
Vertex = (1, -6)
Answer:
Y = mx + b
y = how far up
x = how far along
m = Slope or Gradient (how steep the line is)
b = value of y when x=0
