<p>My textbook mentions that the slope of a linear demand curve gives crucial information regarding price elasticity of demand; namely, that demand is inelastic for steeper curves and elastic for flatter ones.

Elasticity is defined at a point.

$$ \frac{\partial Q}{\partial P} \* \frac{P}{Q} $$

A more or less elastic curve just means that the elasticity is higher or lower in general. For example, if you have the two demand curves

$$ q = -\frac{1}{4}p + 8 $$
$$ q = -\frac{1}{2}p + 12 $$

If you plug in the same price points or quantity points, you will get higher elasticities for the second equation and lower elasticities for the first. So we talk about the second curve being more elastic and the first curve being more inelastic, but its because each is characterized as such by the elasticities at its points.
