Problem
In a slope field, what does the sign of the short line segment drawn at a point (x,y) indicate about a particular solution curve passing through that point?
(a) Whether the curve’s concavity is upward or downward at that point.
(b) The steepness (magnitude) of the curve’s slope, regardless of direction, at that point.
(c) Whether the curve’s instantaneous rate of change is positive or negative at that point.
(d) The exact value of y for the solution at that point.
