Algebra.Com's Answer #392 by usyim88hk(158)![]() ![]() ![]() You can put this solution on YOUR website! You can see the slope and the y-intercept from the equation y = 135+25x easily because it is in the slope-intercept form already... \n" ); document.write( ": \n" ); document.write( "y=mx+b \n" ); document.write( ": \n" ); document.write( "where m is the slope and b is the y-intercept \n" ); document.write( ": \n" ); document.write( "So the y-intercept is 135 and it means that you must pay $135 first in order to rent a car \n" ); document.write( ": \n" ); document.write( "The slope is 25 and it means that for each day the driver has to pay $25 \n" ); document.write( ": \n" ); document.write( "If x is 4 \n" ); document.write( "Then y = 135+25(4) \n" ); document.write( "y = 135+100 \n" ); document.write( "y = 235 \n" ); document.write( "So this means that if the number of days the driver rent the car is 4, then he will have to pay $235 \n" ); document.write( " |
