Which equation can pair with 3x 4y 8 to create a consistent and independent system?

To create a consistent and independent system with the equation (3x + 4y = 8), you need a second equation that has a different slope. For example, you could use the equation (x - 2y = -1). This equation will intersect with the first equation at exactly one point, ensuring that the system is consistent (has a solution) and independent (the equations are not multiples of each other).
