Question

Which system of equations is represented by the graph?

A) y= x2 − 6x − 7
x − y = 1

B) y = x2 − 6x + 7
x + y = −1

C) y = x2 + 6x − 7
x − y = 1

D) y = x2 + 6x + 7
x + y = 1

Answer 1

The answer is D. y = x2 + 6x + 7

x + y = 1

Explanation:

Answer 2

D) y = x² + 6x + 7

x + y = 1

Explanation:

Just simply substitute the solution into the equations to confirm their authenticities.

I am glad to help.
