Question

to get into her tree house, annabeth rests a ladder against the tree. the top of the ladder is 13 feet above the ground. the base of the ladder is 3 from the tree. what is the slope of the ladder

Answer 1

slope = rise/run
the ladder "rises" to 13 feet above the ground
the ladder "runs" 3 feet from the base of the ladder to the tree
so: slope = rise/run = 13/3

Answer 2

13-0
3-0
=
13/3
=
4 1/3
Rise over run you know, y1-y2 over x1-x2
