First, we can rearrange the equation into its y=mx+b form:
-9x-3y=6
1) Add 9x to both sides
-3y=9x+6
2) Divide both sides by -3
y=-3x-2
Now, substitute x for 4 to find the value of y:
y=-3(4)-2
y=-12-2
y=-14
Therefore, when x=4, y=-14

Write in standard form y=2(x-1)^2+6
vlabodo [156]

Answer:

Y=2x+2

Step-by-step explanation:

Im not 100% sure this is correct but what I did was

Y=2(x-1)^2+6

2(x-1) = 2x -2

Y=2x -2^2 +6

Y=2x -4 + 6

-4 + 6 = 2

So y=2x+2 (y=mx+b)

I hope this helps you
