Question

$y = x + 6$
$y = x + 6$
which describes the system of equations above?
consistent and dependent
consistent and independent
inconsistent

Explanation:

A consistent system has at least one solution. Dependent equations are identical, so every point on one line is a solution (infinitely many solutions). The two equations here are exactly the same, and their graphs overlap completely, meaning there are infinitely many solutions.

Answer:

consistent and dependent
