In this section, you will learn how to find a linear approximation to a separable differential equation by sketching a solution curve passing through a given point on a given slope field.
Sketching solution curves in slope fields
Typeset a grid of points with axes where the axes are dashed lines. We don't want solid axes, because the slope at those points may be zero, in which case the student should draw a short horizontal line. Using dashed axes ensures the short lines are visible.
