A steel wire goes between the tops of two walls that are 15 m apart. One wall is 8 m high. The other is 5 m high. What is the slope of the steel wire?
(Leave solution if possible)

"Rise over Run" determines slope.
Difference between the walls' heights is 3m.
Difference between the wall's positions is 15m
3m/15m = 1/5
The taller wall is the first wall though, so the answer becomes negative since the wire is running down and to the right. Therefore, the slope is -1/5.

ok, so the slope is rise over run.
rise is how high it goes (from the top of the shorter one to the top of the higher one)
5m to 8m
so that would b 3
then the run would be how far it would have to go
so that would be 15m since that's how far the two walls are
so the rise over run (slope) would be
3 over 15
3/15
or, if simplified, it would be 1/5
:-D

distance between two tops =squareroot of 15 square-3square =6 root 6
so slope =3 divided by 6 root 6

its pythagorus, from the question you find a triangle that has a side of 15 and a side of 3
15 squared is 225
3 squared is 9
225 + 9= 234
find squared root
15.3 rounded
