What happens when two lines are parallel in a system of equations?

• They have infinite solutions

• They have no solutions

• They intersect at one point

• They intersect at two points

What is the purpose of converting free-response questions to multiple-choice?

• To make them easier

• To focus on theoretical understanding

• To practice the guess-and-check strategy

• To reduce the number of questions

What should you do if a system of equations has no points of intersection?

• Recalculate manually

• Try a different method

• Conclude there are no solutions

• Adjust the constant to find a solution

What is the correct approach if a system of equations intersects at one point?

• It has infinite solutions

• It has two solutions
