Algebra.Com's Answer #179999 by richwmiller(17219)![]() ![]() You can put this solution on YOUR website! You can have a decimal as the slope. It often is. \n" ); document.write( "You have to subtract y's and x's\r \n" ); document.write( "\n" ); document.write( "The y's are 7 and -12 \n" ); document.write( "The x's are 5 and -7 \n" ); document.write( "the rise y's are the numerator and the run the x's are the denominator \n" ); document.write( "your answer is correct but you made a mistake in setting it up. \n" ); document.write( "you started with the second point \n" ); document.write( "(-12-7)/(-7-5)=-19/-12\r \n" ); document.write( "\n" ); document.write( "You forgot the minus in the 7 of the denominator otherwise it would be +2 and not -12\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
