A school system is reducing the amount of dumpster loads of trash removed each week. In week 5, there were 45 dumpster loads of
Anastaziya [24]
For the answer to the question above,
 let x = number of weeks let y = amount of waste.
The linear equation may be expressed as,y = mx + b
 m and b are the slope and y - intercept, respectively. Substituting the corresponding values,
   (Week 5)                     45 = 5m + b
   (Week 10)                   30 = 10m + b
Solving for m and b gives the values as m = -3 and b = 60. Thus, the equation is 
 y = -3x + 60
So the answer to this question is the third one
