you can find  replcing x and y by the coordinates of the points
A : 5.-2 + 5 ≠9 not solution
B : 5.1 + 4 = 9 so 3.1 + 2.4 = 11 ≠4 not solution
C: 5.2 +  = 9  so 3.2 + 2.-1 = 4 both are right then C is solution
D: 5.4 - 4 = 16 ≠ 9 not solution

Answer:

(C) (2,-1)

Step-by-step explanation:

The given system of equations is :

\(5x+y=9\)                            (1)

and \(3x+2y=4\)                  (2)  

Multiply equation (1) with 2 and then subtract equation (2) from it, we get

⇒\(10x+2y-3x-2y=18-4\)

⇒\(7x=14\)

⇒\(x=2\)

Substitute the value of x=2 in equation (1), we get

⇒\(5(2)+y=9\)

⇒\(10+y=9\)

⇒\(y=-1\)

Therefore, x=2 and y=-1. that is (2,-1).
