Given a slope field diagram, identify which differential equation produces it, or given a differential equation, sketch/draw the slope field at indicated points.
Shown above is a slope field for which of the following differential equations? (A) $\frac { d y } { d x } = x y + x$ (B) $\frac { d y } { d x } = x y + y$ (C) $\frac { d y } { d x } = y + 1$ (D) $\frac { d y } { d x } = ( x + 1 ) ^ { 2 }$
Shown above is a slope field for which of the following differential equations? (A) $\frac { d y } { d x } = \frac { y - 2 } { 2 }$ (B) $\frac { d y } { d x } = \frac { y ^ { 2 } - 4 } { 4 }$ (C) $\frac { d y } { d x } = \frac { x - 2 } { 2 }$ (D) $\frac { d y } { d x } = \frac { x ^ { 2 } - 4 } { 4 }$
