I think it may be true, please correct me if i am wrong
The answer is C and D
First we must make one side of the equation zero, so we subtract 7 on both sides of the equation, making the equation 9x^2 - 6x - 6 = 0
Then we will use the quadratic formula to find the answers.
using the Quadratic Formula where:
a = 9, b = -6, and c = -6
and the formula is 6 +- 
Since a coordinate is written as (x,y) then the x-value is 14 and the y-value is 448. Therefore, the answer is 448. Hope I helped!
