slope = $-\dfrac{1}{20}$

Work Step by Step

The slope is negative since a drop is involved (falling from left to right). The slope can be computed by dividing the drop (which will be represented by a negative number) by the horizontal distance : slope = $\dfrac{-54\text{ ft}}{1080\text{ ft}}=-\dfrac{1}{20}$
