The price of a 2-hour plumbing repair job is $130 and the price of a 5-hour job is $250. Find and interpret the slope of the line through (2, 130) and (5, 250).
\n" ); document.write( "-------------
\n" ); document.write( "Your \"x\" values are time.
\n" ); document.write( "Your \"y\" values are cost
\n" ); document.write( "------------------------------
\n" ); document.write( "slope = [change in cost/change in time] = (250-130)/(5-2) = 120/3 = 40
\n" ); document.write( "----------------------------------------
\n" ); document.write( "This slope tells you the cost increases by $40 for each additional
\n" ); document.write( "hour of work.
