Remember that quantity of questions answered (as accurately as possible) is the most important aspect of scoring well on the ACT, because each question is worth the same amount of points. Determine whether the lines through each pair of points are parallel. A system of equations is two equations and the point of intersection is the solution. Determine if the ordered pair (0, 2) is a solution of -3x + y = 2. The solution is detailed and well presented.
