Question

The cost (C) of a heating bill is determined by a linear equation. If the cost increases 3 dollars per day for an increase of 6 degrees a year, what is the slope of the graph of the equation? (Use 365 days for the year).

Answer 1

The best number for slope would be 1,095. If the cost of heating is $3 per day, and there are 365 days in a year, then the total cost would be $1,095. 

Hope this helps!
