Sketching Slope Fields Practice Test

Slopes are constant on diagonals $y-x=c$; slopes increase as $c$ increases.

Slopes are zero on $x=0$ and $x=1$; slopes are positive for $0<x<1$ and negative for $x>1$ or $x<0$.

Slopes are zero on $y=0$ and $y=1$; slopes are positive for $0<y<1$ and negative for $y>1$ or $y<0$.

Slopes are zero only at the origin; slopes are positive in Quadrants I and III and negative in Quadrants II and IV.

Slopes depend on both variables with zero slopes on $y=x$; slopes change sign across $y=x$.
