Question

A line has a rise of 6 and a slope of 1/20 what's the run

Answer 1

slope = rise / run
slope = 1/20
rise = 6

now sub
1/20 = 6 / run(r)...now u cross multiply because this is a proportion
(1)(r) = (6)(20)
r = 120 <==the run

** and take notice...proportions are nothing but equivalent fractions
1/20 = 6/120
