Aweight of 15 ounces stretches a spring 10 inches. a weight of 24 ounces stretches the same spring 16 inches. how many inches does the spring stretch per ounce of additional weight?

16-10 = 6 inches

24-15  = 9 ounces

it stretches 6 inches when 9 ounces are added

 divide 6 inches by 9 ounces

6 / 9 = 0.67 inches per ounce

easy its decreasing

because its top point is at the to of the graph on the left side (atleast from the veiw i see it) now if that top point wast in the lower part of the graph it would be increasing hope this have a nice day
