Shannon graphed the system of equations. 7x – 4y= –8 y = x – 3 what is the closest approximate solution to the system of equations? (–5, –7.2) (–5, –6.8) (–5, –6.2) (–5, –5.9)

we have

-------> equation A

------------> equation B

we know that

The solution of the system of equations is the intersection point both graphs

so

Using a graphing tool

see the attached figure

The solution is the point  

therefore

the answer is

the closest approximate solution to the system of equations is

find the magnitude of the trig term
