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
