The graphical representation of a system of two linear equations is two lines. These two lines can (1) interesct at a point (x, y) (2) not intersect and be parallel (no solution) (3) sometimes turn out to be the same line (infinitely many solutions).
These are the only possibilities for a system of two linear equations because when graphed, they will only do these three things.
It would be J. This is because the opposite of -3.5 would be 3.5 and the absolute value is just a positive integer or positive number so that would be 3.5 as well so its J
