On a canoe trip, rita paddled upstream (against the current) at an average speed of 2 mi/h relative to the riverbank. on the return trip downstream (with the current), her average speed was 3 mi/h. find rita's paddling speed i'm still water and the speed of the current

Which statements are true? check all that apply. the line x = 0 is perpendicular to the line y = –3. all lines that are parallel to the y-axis are vertical lines. all lines that are perpendicular to the x-axis have a slope of 0. the equation of the line parallel to the x-axis that passes through the point (2, –6) is x = 2. the equation of the line perpendicular to the y-axis that passes through the point (–5, 1) is y = 1.
