I’m not too good at this answer these correctly

This picture should be able to show you completely

Ifound this on google “that means that the graph of a function with direct variation has these features: it is a straight line: because the slope is the ratio y/x = k. it passes through the origin (0,0): because y = kx = k (0) = 0.” i hope this you for what your looking for

1.3 and 1 1/3 are both closest to 1. hope this ; )
