Which system of equations is represented by the graph? (2 points)
y = x2 - 6x - 7
x - y = 1
y = x2 - 6x + 7
x + y = -1
y = x2 + 6x - 7
x - y = 1
y = x2 + 6x + 7
x + y = 1

Which system of equations is represented by the graph 2 points y x2 6x 7 x y 1 y x2 6x 7 x y 1 y x2 6x 7 x y 1 y x2 6x 7 x y 1 class=

Respuesta :

The system of equations is represented by the graph y= x2 + 6x +7 and x + y  = 1
Two equation accept the values (-6,7) and (-1,2).

Answer: [tex]y=x^2+6x+7\\ x+y=1[/tex]


Step-by-step explanation:

From the given graph we can see (-6,7) and (-1,2) are the intersection points of the a curve and a line .

Since we know that when the graphs of two equations cross, the point of intersection lies on both lines, means that it is a possible solution for both equations.

From all the options only last options satisfy the given intersection points.

For (-6,7) , [tex](-6)^2+6(-6)+7=7[/tex]

[tex]-6+7=1[/tex]

Hence, [tex]y=x^2+6x+7\\ x+y=1[/tex], is  the system of equations is represented by the graph.

Rest of the other options do not satisfy the given intersection points.
