Question

a group of scientists studied the amount of erosion at a beach. the scientists determined that the equation y=-0.5x+26 models the amount of shoreline, y, in feet, x decades after 1950. which statement is true based on the model?

Answer 1

Take into account that x represents the number of decades after 1950. Moreover, consider that -0.5x is a decrease in the values of y, each decade.

Then, you can conclude that each decade, that is, every 10 years, the shoreline reduces 0.5 feet.

Hnece, you have:

The shoreline is reduced by 0.5 foot every 10 years
