- Yes, the graph shows a proportional relationship because it is a straight line passing through the origin (0,0), which means y is directly proportional to x.
- No, the graph does not show a proportional relationship because it is a curved line and does not pass through the origin; the ratio of y to x is not constant.
- No, the graph does not show a proportional relationship because although it is a straight line, it does not pass through the origin; there is a non-zero y-intercept.
- No, the graph does not show a proportional relationship because it is not a straight line and does not pass through the origin; the rate of change is not constant.
