Please answer my question, and if you can please provide an explanation so I can learn from it. 50 POINTS. Amy is helping plan her school's new basketball court. The west edge of the basketball court is located on the line y = −4x. The east edge cannot intersect with the west edge. On which line could the east edge be located?

y − 4x = −200
−4x − y = −50
4x − y = −200
−y + 4x = −50
