Which is the graph of the solution set of 5x + 8y > 50? On a coordinate plane, a dashed straight line with a negative slope goes through (0, 6) and (10, 0). Everything below and to the left of the line is shaded. On a coordinate plane, a solid straight line with a negative slope goes through (0, 6) and (10, 0). Everything above and to the right of the line is shaded. On a coordinate plane, a dashed straight line with a negative slope goes through (0, 6) and (10, 0).
