Algebra.Com's Answer #49613 by ptaylor(2198) You can put this solution on YOUR website! I need to find the y-intercept of 3x+y=4. \r \n" ); document.write( "\n" ); document.write( "This is the equation of a straight line. The standard form for this equation is :\r \n" ); document.write( "\n" ); document.write( "y=mx+b \n" ); document.write( "Where m is the slope and b is the y-intercept. This is called the slope- intercept form for a straight line.\r \n" ); document.write( "\n" ); document.write( "Now we need to put your equation into standard form:\r \n" ); document.write( "\n" ); document.write( "3x+y=4 subtract 3x from both sides\r \n" ); document.write( "\n" ); document.write( "3x-3x+y=-3x+4 \n" ); document.write( "y=-3x+4 This is now in standard slope-intercept form and we can see that the y-intercept is +4 --------------ans\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Again, I sure hope this helps-----ptaylor\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
