Aschool system is reducing the amount of dumpster loads of trash removed each week. in week 5, there were 45 dumpster loads of waste removed. in week 10, there were 30 dumpster loads removed. assume that the reduction in the amount of waste each week is linear. write an equation in function form to show the amount of trash removed each week.

We are given with two conditions: week 5 having 45 dumpster loads removed and week 10, with 30 loads of dumpsters. we translate this into points (5,45) and (10,30). we find the slope between, we have 15/-5 or -3. we plug in to the equation y-y1 = m (x-x1) where m is the slope. y - 45 = -3 *(x-5). we simplify and get y-45 = -3x +15 or y +3x -60 = 0.
