Answer:
slope = -3/20
Step-by-step explanation:
in order to get the y for the right triangle you do 9-6, which is 3
so now for the triangle we have y = 3, x = 20
slope = rise/run or y/x
slope = 3/20, but we're not done yet because you notice the slope is negative on the zip line because y goes down as x goes up, or it goes down as you go right.
so the slope is -3/20
