we have

[tex]y=-\frac{5}{2}x-7[/tex] ------> equation A

[tex]x+2y=4[/tex] ------> 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 [tex](-4.5,4.25)[/tex]

therefore

the answer is the option A

[tex](-4.5,4.25)[/tex]
