A train's travel is represented by the equation y = 17.5x, where y represents the total number of miles the train travels in z hours. If this relationship is graphed on a coordinate plane, which statement is true?
The graph passes through (0,0) and (17.5, 1), and the slope represents the train traveling at a rate of 1 mile every 17.5 hours.
The graph passes through (0,0) and (17.5, 1), and the slope represents the train traveling at a rate of 17.5 miles every hour.
The graph passes through (2,35) and (4.70), and the slope represents the train traveling at a rate of 1 mile every 17.5 hours.
The graph passes through (2, 35) and (4,70), and the slope represents the train traveling at a rate of 17.5 miles every hour.
