Which one of these is not a characteristic of a p r o p o r t i o n graph it passes through the o r i g i n (0 ,0 )the y values are always larger than the x it is a straight line why y/x is the same for all points on the line

The characteristic "the y values are always larger than the x" is not correct for a proportion graph. In a proportion graph, the ratio of y to x remains the same for all points on the line, and the line passes through the origin (0, 0). Additionally, it is a straight line.
