Which graph represents the solution set for the system s + l < 30 and 8s + 12l ≤ 160? on a coordinate plane, 2 straight lines are shown. the first dashed line has a positive slope and goes through (negative 30, 0) and (0, 30). everything to the left of the line is shaded. the second solid line has a negative slope and goes through (negative 25, 30) and (negative 10, 20). everything to the left of the line is shaded. on a coordinate plane, 2 straight lines are shown. the first solid line has a negative slope and goes through (5, 10) and (20, 0). everything below and to the left of the line is shaded. the second dashed line has a negative slope and goes through (0, 30) and (30, 0). everything above and to the right of the line is shaded. on a coordinate plane, 2 straight lines are shown. the first solid line has a negative slope and goes through (5, 10) and (20, 0). everything above and to the right of the line is shaded. the second dashed line has a negative slope and goes through (0, 30) and (30, 0). everything below and to the left of the line is shaded. on a coordinate plane, 2 straight lines are shown. the first solid line has a negative slope and goes through (5, 10) and (20, 0). everything below and to the left of the line is shaded. the second dashed line has a negative slope and goes through (0, 30) and (30, 0). everything below and to the left of the line is shaded.
