Answer
The solution of the system of equations is approximately the ordered pairs x,y: $(5.6,-5.4)$
Work Step by Step
By looking at graph, the solution of the system of equations is approximately the ordered pairs x,y: $(5.6,-5.4)$.
If we want to check the solution we can substitute this point into the equations:
1) $100x+4.5y=540$
1) $100(5.6)+4.5(-5.4)=560-24.3=535.7\approx540$
2) $1.05x+1.1y=0$
2) $1.05(5.6)+1.1(-5.4)=5.88-5.94=-.06\approx0$
The solution of the system of equations is approximately the ordered pairs x,y: $(5.6,-5.4)$
