Question

Which of the following situations would give you a system of equations that have at least 2 solutions?

a) Two lines are parallel and have different y-intercepts.
b) Two lines have the same slope and both pass through the origin.
c) Two lines are perpendicular and have the same y-intercept.
d) Two lines have negative slopes and different y-intercepts.

Answer 1

Answer: B. Two lines have the same slope and both pass through the origin.

Step-by-step explanation: This would mean that the lines are on top of each other; they would share every point (which means that they would have a system of equations with infinite solutions.) ∞ > 2, so, it answers the question!
