Final answer:
A freehand curve can be sketched by connecting a series of points at regular intervals along the path of the curve.
Step-by-step explanation:
A(n) freehand curve may be sketched freehand by connecting a series of points at intervals of 1/4" to 1/2" along the path of the curve. This is a common practice in drawing curves or graphs by hand, especially in situations where the precise equation of the curve is not known.
