Question 824674: judith and marie are helping their friends change the light bulbs on a wall fixture. They placed the base of the ladder 3 feet from the wall. The top of the ladder meets the wall 8 ft above the ground. What is the slope of the ladder?
AND
Danny's kites is 45 ft in the air. The slope of the string is 9/2. How far away is Danny from the spot on the ground directly below the kite?

----
Slope is change in y/change in x, or "rise/run"
AND
Danny's kites is 45 ft in the air. The slope of the string is 9/2. How far away is Danny from the spot on the ground directly below the kite?
-------
y/x = 9/2
45/x = 9/2

problem 1:
---
slope = dy/dx
slope = 8/3
---
problem 2:
---
slope = dy/dx
9/2 = 45/dx
dx = 45/(9/2)
dx = 10
Danny is 10 feet away from the spot on the ground directly below the kite

NOTE TO STUDENT:
slope is a signed (+ or -) quantity, but these problem statements do not give information that would allow anyone to determine whether the slopes are positive or negative, in reference to the Cartesian plane.
