A slope field is observed to have the following features: • The slope is zero along both coordinate axes. • In Quadrants I and III the segments tilt upward to the right. • In Quadrants II and IV the segments tilt downward to the right. Which differential equation could produce this slope field? a) dydx=x+y\dfrac{dy}{dx}=x+y b) dydx=x2y2\dfrac{dy}{dx}=x^{2}y^{2} c) dydx=xy\dfrac{dy}{dx}=xy d) dydx=yx\dfrac{dy}{dx}=\dfrac{y}{x}
