I was given some points on a graph. The points were in year and weight of garbage format. points:- (1991, 523), (1992, 528), (1993,534), (1994, 542), (1995, 551), (1996,562), (1997, 574), (1998, 583), (1999, 594). I plotted these points and made a line of best fit. THe questions are:-
a) Determine an algebric expression that models the amount of waste received each year? (the x axis is years, and the y - axis is weight)
b) Use your model to make a prediction of the last year that the landfill site handled less then 500t of waste.
c)Using the predictions of model, write a short newspaper article on the effectiveness of recycling campaign.
