Determine which graph defines y as a function of x. A.) A graph with an x-axis and a y-axis ranging from -6 to 6. There are five marked points in the first quadrant with the coordinates (6, 5), (1, 3), (6, 2), (4, 3), and (2, 1). B.) A graph with an x-axis and a y-axis ranging from -6 to 6. There are five marked points in the first quadrant with the coordinates (4, 5), (3, 4), (1, 2), (6, 2), and (3, 1). C.) A graph with an x-axis and a y-axis ranging from -6 to 6. There are five marked points located in the first quadrant at the coordinates (1, 5), (1, 4), (3, 1), (4, 3), and (6, 2). D.) A graph with an x-axis and a y-axis ranging from -6 to 6 has five marked points. There are four marked points in the first quadrant with the coordinates (1, 5), (3, 4), (6, 2), and (2, 1). There is one marked point in the fourth quadrant with the coordinate (4, -1)
