Question

solve the systems of linear equations by graphing y=-5/2x-7 x+2y=4 what is the solution to the system of linear equations A. (-4.5,4.25) B. (-1.7,-2.8) C. (0,-7) D. (3,0.5)

Answer 1

we have

`y=-(5)/(2)x-7` ------> equation A

`x+2y=4` ------> equation B

we know that

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

Using a graphing tool

see the attached figure

The solution is the point
`(-4.5,4.25)`

therefore

the answer is the option A

`(-4.5,4.25)`

Answer 2

The appropriate choice is
A. (-4.5, 4.25)
