(10 points) Match the slope fields below with their differential equations (the horizontal variable is r, the vertical variable is y). Also indicate which two equations do not have matches. III I, II, III, IV Reasoning Equation V, VI, or "none" dy = cy dx dy =y- C dy dy =1-y dx dy = cos y dr dy = y(y2 -1) dy = cos x dy = y(y - 1)
