weight (kg)










A scatterplot has a horizontal scale labeled "width in centimeters" from 7 to 10 in increments of 0.5 and a vertical scale labeled "weight in kilograms" from 100 to 300 in increments of 20. Six points are plotted with approximate coordinates as follows: (7, 295); (7.7, 215); (8.4, 205); (8.7, 200); (9.3, 200); (9.8, 150).
