Hi,

The cost for an exterminator to treat a 1500 sq ft home is $65.00 and the cost for a 3000 sq ft home is $80.00. 

 (3000, 80)

 (1500, 65) Slope m = 15/1500 = 1/100

In general:  y = mx + b

   || Where C is the Cost and A the area of the home

   |Using (3000,80) to solve for b

80 = 30 + b

50 = b, the y-intercept



C = = $71
