Which is the equation of a line perpendicular to the line with the equation 3x+4y=8

Which equation represents a line that is parallel to the line whose equation is 3x-2y=7( show all work)

Kayla wants to find the width, ab, of a river. she walks along the edge of the river 65 ft and marks point c. then she walks 25 ft further and marks point d. she turns 90° and walks until her location, point a, and point c are collinear. she marks point e at this location, as shown. (a) can kayla conclude that δ and δ are similar? why or why not? (b) suppose de = 15 ft. what can kayla conclude about the width of the river?
