The steps are to first distribute the 1/3 into (x-9) and then to move the +6 on the left over to the right:
First distribute:
y + 6 = 1/3(x-9) becomes y + 6 = 1/3x-3
Now subtract 6 from both sides:
y = 1/3 x - 3 - 6
y = 1/3 x - 9
Usually, the function of a parabola is y=ax^2+bx+c. With your three given points, which I don't know, plug in your x's and y's to come up with three quadratic equations. Using those equations, you use algebra to find out what a, b, and c equal. Once you have a numerical answer, insert them in the usual quadratic function to have your answer.

Answer:
x = -8
Step-by-step explanation:
4( 3x +5 ) - 3 = 9x -7
Distribute
12x +20 -3 = 9x -7
Combine like terms
12x+17 = 9x-7
Subtract 9x from each side
12x-9x +17 = 9x-9x-7
3x +17 = -7
Subtract 17 from each side
3x+17-17 = -7-17
3x = -24
Divide each side by 3
3x/3 = -24/3
x = -8
