You can put this solution on YOUR website! I need help finding the conic intersection of these system of equations, please!
x^2 - y^2 = 9
8y = 4x - 12 --> 2y = x - 3 --> x = 2y + 3
------------
The problem has nothing to do with the conic intersection.
Just find the solution.
x^2 - y^2 = 9
x = 2y + 3
---
Sub for x in the 1st eqn
(2y+3)^2 - y^2 = 9
3y^2 + 12y + 9 = 9
3y^2 + 12y = 0
y = 0, y = -4
-------
x = 2y + 3
--> (3,0), (-5,-2)
