Billy graphed the system of linear equations to find an approximate solution. y =-7/4 x +5/2 y =3/4 x – 3

Step-by-step explanation:

we have

------> equation A

------> equation B

Remember that

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

Using a graphing tool

see the attached figure

The intersection point is

the answer on edu is (2.2,-3.35) and (2.2,-1.4) so [B and C are correct]

I hope this helps you!

Step-by-step explanation:
