Algebra.Com's Answer #54998 by wodkit02(9)![]() ![]() ![]() You can put this solution on YOUR website! Since we are given the slope and the y-intercept, we have the equation in slope-intercept form: y = mx + b\r \n" ); document.write( "\n" ); document.write( "m = 3/4; b (or the y-intercept) = -3 \n" ); document.write( "y = \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Standard form looks like this : Ax + By = C, where A, B, and C are all integer constants. Let's get y and x on the same side.\r \n" ); document.write( "\n" ); document.write( "y = \n" ); document.write( "\n" ); document.write( "- \n" ); document.write( "\n" ); document.write( "Now we need to multiply everything by 4 so the fraction can become an integer:\r \n" ); document.write( "\n" ); document.write( "4 * - \n" ); document.write( "-3x + 4y = -12\r \n" ); document.write( "\n" ); document.write( "Since all the constants are integer values, we are done. \n" ); document.write( " |
