The equation y = x + a is graphed in the xy-plane, where a is a positive constant. a second
equation, y = x - a, is graphed in the same ry-plane. how do the slope and y-intercept of the
graph of the first equation compare with the slope and y-intercept of the graph of the second
equation?

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?
