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.

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!

Hope this was helpful! Let me know if you have any further questions. :)

It would be D because you need to multiply 38 and 50. But x is the length of one classroom, and because we don't know it, you would get 38(50-x).

Good luck!!
