It costs $24 per hour plus a flat fee of $23 for a plumber to make a house call. After writing an equation for this situation, what is the total cost to have a plumber come to a house for 10 hours?\r
\n" ); document.write( "\n" ); document.write( "..\r
\n" ); document.write( "\n" ); document.write( "You can think of this relationship as a straight line applying the standard form, y=mx+b, with m=slope and b=y-intercept.\r
\n" ); document.write( "\n" ); document.write( "Picture a straight line graph with cost on the y-axis and hours on the x-axis. At zero hours, just when the plumber enters the house, the cost is already $23, from hereon, every hour costs an additional $24. This is the slope in the equation which is as follows:
\n" ); document.write( "y=24x+23
\n" ); document.write( "Total cost for 10 hours=24*10+23=$263\r
\n" ); document.write( "
