Can someone me answer this dejah is proving that perpendicular lines have slopes that are opposite reciprocals. she draws line s and labels two points on the line as (-a, 0) and (0, b). the slope of line s is rotate line s 90° clockwise about the origin to get line t. the labeled points on line s map to (0, a) and on line t. the slope of line t is the slopes of the lines are opposite reciprocals because the product of the slopes is i know the first answer is b/a. is the second point for line t (b, 0) or (-b, 0)? i'm not sure what that one is.
