Algebra.Com's Answer #550485 by josgarithmetic(39620)![]() ![]() ![]() You can put this solution on YOUR website! You might want y to represent cost of renting the lawnmower.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Let y be cost \n" ); document.write( "Let x be days of rent\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "The $4 is included with the days at x=1, but would be not included for x=0, or zero days of rent. The flat fee would still be used, but in practice, a person would not be charged any such $18 if he not renting any lawnmower.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "At x=0, y=18; and for each 1 day increase, the $4 per day is applied, which becomes the slope of the equation; the 18 is the y-intercept.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " |
