-7 - 3x = 9x(x + 2)
Standard Form:
-9x^2 - 21x - 7 = 0
Answer:
A. 3(y+2)
Step-by-step explanation:
B wouldn't work because it would be safe to assume that it represents the quintuple of the sum. C also wouldn't work because although the y is tripled, the 2 isn't. And D wouldn't work because it is only tripling 2.
A should be your answer since you are distributing the number 3 which is the same thing as a triple to get the sum of the answer which is 3y + 6.
To solve this problem you must apply the proccedure shown below:
If
, you have that:

Because
and 
Therefore, as you can see, the answer is: 
Answer:
The answer to your question is y = -2x + 9
Step-by-step explanation:
A (9, 9)
B (-2, 13)
Process
1.- Find the slope
m = 


m = - 2
2.- Find the line equation
(y - y1) = m (x - x1)
y + 9 = -2 (x - 9) y + ? = [ ] ( x + [ ])
y + 9 = - 2x + 18
y = - 2x + 18 - 9
y = -2x + 9
Nun man I think you could be trippin
