Hi I'm just very very confused here! I've tried and I just can't figure it out.

Hello I just figured them out! the first one is B and the second is A!
What have you done?
Did you set the y of one equation equal to the y of the other?
For the 2nd that is, x^2-3x-1 = 8x-1
x^2 - 11x = 0
did you factor this to x(x-11) = 0 ???
Now the answers are obvious
