Consider the differential equation dydx=2x\displaystyle \frac{{{\left.{d}{y}\right.}}}{{{\left.{d}{x}\right.}}}=-{2}{x}

(A) At the point (0.5,0.5)\displaystyle {\left({0.5},{0.5}\right)}, the direction field has a slope of  
(B) At the point (1,0.5)\displaystyle {\left({1},-{0.5}\right)}, the direction field has a slope of  
(C) Use your answers above to help choose the correct direction field for the differential equation.
