A zip line is a taut rope or cable that you can ride down on a pulley. The zip line at the right goes from a 9 foot tall tower to a 6 foot tall tower. The towers are 20 feet apart. What is the slope of the zip line?

slope is rise over run, or change in X over change in Y
the change in rise is 3 feet, the change in distance is 20 feet
the slope of the zip line is -3/20
or think of the 2 towers as points on a coordinate grid
(0, 9) and (20, 6)
(y1-y2)/(x1-x2)=(9-6)/(0-20)=3/(-20)=(-3/20)

Slope is the ratio of rise to run.
In this case the rise is 3 feet (9-6)
The run is the horizontal distance which is 20 feet.
The slope is calculated by dividing the rize by the run or 3/20
or 0.15

Slope = rise / run
rise = 9-6 = 3ft
run = 20 ft
thus, slove = 3/20

slope is rise over run, 9-6 = 3 over 20. if you need it as an angle, 3/20 is the tangent of the angle, so Π= 8.53°.
