Answer:
Could you explain it another way?
Step-by-step explanation:
Step-by-step explanation:
1. y--7=-2(x-0)
y+7=-2x
y=-2x-7
2. y--3=-2(x-1)
y+3=-2x+2
y=-2x+2-3
y=-2x-1
Answer:
A
Step-by-step explanation:
Answer:
a = -
, b = - 
Step-by-step explanation:
To obtain the required form use the method of completing the square
add/ subtract ( half the coefficient of the x- term)² to x² - 9x
y = x² + 2(-
)x +
-
+ 14
= (x -
)² -
+ 
= (x -
)²-
← in the form (x + a)² + b
with a = -
and b = -
