A technician charges $25 per hour plus $50 for a house call to repair home computers. Make a table and a graph to show the cost for 1,2,3, and 4 hours of home computer repair service. Is there a direct variation
The graph starts at $75 since the price for call is $50 and 1 hour of work costs $25.
Direct variation is only noticeable at the beginning of the graph after that the function is linear.
