In 200, a government program cost taxpayers $150 billion, and in 2010 is cost $300 billion. Find a linear function M that models these costs, in billion, x years after 2010

if the data shows fx mx + b

c = 300 = - 1 (150) + b

300 = - 150 + b

500 = b

Step-by-step explanation:

m = change in c / divided by the change x we find this = 300-150 / 2010/-2000 = - 1.005 year of change

= m = - 1 year per billion

This means if the year shows an old data = - 1.005 billion then it will show an increase for the duration of - 1.005 billion = 150 billion.

m=-1
