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)

we have

------> equation A

------> 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

therefore

the answer is the option A

homozygous. one is homozygous, while two is heterozygous.
