How to Find the length of the median of each trapazoid

Identify an equation in point slope form for the line perpendicular to y=3x+5 that passes through (4,-1)

Need on this geometry question. explain how you did it.

Type the correct answer in each box. spell all words correctly. a sequence of transformations maps ∆abc onto ∆a″b″c″. the type of transformation that maps ∆abc onto ∆a′b′c′ is a . when ∆a′b′c′ is reflected across the line x = -2 to form ∆a″b″c″, vertex of ∆a″b″c″ will have the same coordinates as b′.
