Which equation does the graph below represent? (5 points) A coordinate grid is shown. The x axis values are from negative 5 to positive 5 in increments of 1 for each grid line, and the y axis values are from negative 15 to positive 15 in increments of 3 for each grid line. A line is shown passing through the ordered pairs negative 4, 12 and 0, 0 and 4, negative 12. y = fraction negative 1 over 3 x y = −3x y = 3x y = fraction 1 over 3 x
