Answer:
y = x -6
Step-by-step explanation:
The question is asking what system of equations is equivalent to the quadratic given, where one of the equations in the system is y = x^2 -1.
Let's say the other equation is ...
y = mx +b
So, equating the values of y, we would have ...
x^2 -1 = mx +b
Subtracting the right side gives ...
x^2 -mx -1 -b = 0
Now, we can equate coefficients to y=x^2 -x +5 and we will see that ...
-mx = -1x ⇒ m = 1
-1 -b = +5 ⇒ b = -6
The other line has the equation ...
y = x -6
