Question

PLS HELP! If Cyrus knows that △ABC∼△EDC and AB¯¯¯¯¯¯¯¯∥ED¯¯¯¯¯¯¯¯, how can he prove that line m passing through AB¯¯¯¯¯¯¯¯ has the same slope as line l passing through ED¯¯¯¯¯¯¯¯?

Answer 1

AB and DE are parallel because they have the same slope.

Explanation:

Slope of the line AB :

`=\frac{\text{rise} }{\text{run} } =(CA)/(-BC) =(12)/(-8) =-(3)/(2)`

Slope of the line DE :

`=\frac{\text{rise} }{\text{run} } =(CE)/(-DC) =(9)/(-6) =-(3)/(2)`
