Question

PLSSS HELP

In the figure below AB || CD. Select a correct expression for the slope of CD.
(AB and CD have lines over the top of it)

Answer 1

slope =
`(BE)/(AE)`

Explanation:

slope m is calculated as

m =
`(rise)/(run)`

• Parallel lines have equal slope

then slope of CD = slope of AB

rise ( vertical ) of line AB is BE

run ( horizontal ) of AB is AE

slope of AB =
`(BE)/(AE)`

since the slopes of AB and CD are equivalent , then

slope of CD =
`(BE)/(AE)`
