Respuesta :

There are 2 ways we can answer this. The first one is by the given known coordinates we can make and get the equation. Next we can use the known coordinate and substitute it to the all given equations. It appears that only the third option is true after substituting the values. So the answer is C.      

C. y = x^2 + 6x − 7 
x − y = 1

Answer:

C. y = x2 + 5x + 3

   6x + y = −27

Step-by-step explanation:

If the answers are as follows, and you have the same graph then the answer should be C.

A. y = x2 − 5x − 3

   6x − y = −27

B. y = x2 − 5x + 3

   6x − y = 27

C. y = x2 + 5x + 3

   6x + y = −27

D. y = x2 + 5x − 3

   6x + y = 27
