Answer: Graph of two lines that intersect at the point (negative 1, 1).
Step-by-step explanation:
The given system of linear equations :
Multiply equation (1) by 3 , we get
Subtract equation (2) from (3), we get
Divide both sides by 7 , we get
x=-1
Put value of x in (1), we get
⇒ both lines are intersecting at (x,y)=(-1,1)
∴ The correct graph of the given system of equations : graph of two lines that intersect at the point (negative 1, 1)
