    The document contains 14 multiple choice questions about linear equations in two variables. Question 7 asks for the value of k if two given lines are parallel. Question 8 asks for the value of c that would make a pair of equations have infinitely many solutions. Question 9 asks which equation could be the second one of a pair of dependent linear equations given the first. Question 10 provides a pair of linear equations and asks which one has a unique solution of x=2, y=-3.
