Frederick wants to solve this system of equations. y=x²-8x-9. He solves x²-8x-9=0 to find the x-values, and then substitutes those values into y=x² to find the y-values. Use the drop-down menus to complete the explanation of why Frederick's work cannot be used to find the solution of the system of equations.
1) The equation x²-8x-9=0 does not represent the system of equations y=x²-8x-9 and y=x².
2) The equation x²-8x-9=0 does not have any real solutions.
3) The equation y=x²-8x-9 does not have any real solutions.
4) The equation y=x² does not have any real solutions.
