Question

Axes should be drawn in _____ and labeled to show ______

Answer 1

I'm not sure about what axes should be drawn in (that's more of an instructor's preference - some like them drawn in color while others don't care). Axes should be labeled to show any number of things - units (in case the axes represent something measurable, such as inches or miles), increments (making tick marks for ones, fives, etc.), or simply which axis is which (the x- and y-axes, for example).
