Algebra.Com's Answer #179516 by richwmiller(17219)![]() ![]() You can put this solution on YOUR website! It looks like you copied the problem incorrectly. \n" ); document.write( "There was no m (number of minutes)in your formula. \n" ); document.write( "I fixed that. \n" ); document.write( "the y intercept is when y=0 \n" ); document.write( "in this case when c=0 \n" ); document.write( "0=.05m+4.95\r \n" ); document.write( "\n" ); document.write( "multiply both sides by 100 (this step is not necessary it is just to eliminate decimals) \n" ); document.write( " subtract 495 from both sides \n" ); document.write( "-495=5m \n" ); document.write( "divide by 5 \n" ); document.write( "-99=m \n" ); document.write( "-99 is the y intercept \r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
