A system of equations has infinitely many solutions. If 2y – 4x = 6 is one of the equations, which could be the other equation?

y = 2x + 6
y = 4x + 6
–y = –2x – 3
–y = –4x + 6

First rewrite 2y − 4x = 6 as y − 2x = 3, so y = 2x + 3.

The third choice, −y = −2x − 3, is equivalent (multiply both sides by −1) to y = 2x + 3, so the two equations are the same line and have infinitely many solutions.
