Answer:

(2,-1)

Step-by-step explanation:

Multiply first equation by 2:

10x + 2y = 18

Subtract the second equation from this so that the 2y terms cancel:

10x - 3x = 18 - 4

7x = 14

x = 2

Plug into first equation to find y:

5(2) + y = 9

10 + y = 9

y = -1

The answer is (2,-1)

You will need to find the equations of the perpendicular bisector of the two sides and then find the intersection of those two lines. Choose two sides and use midpoint formula to find their midpoints.
