Algebra.Com's Answer #455929 by Cromlix(4381)![]() ![]() You can put this solution on YOUR website! Using y - b = m(x - a) \n" ); document.write( " y - 0 = -1/2(x - 4) \n" ); document.write( " y = -1/2x + 2 \n" ); document.write( "Where the line cuts the y axis \n" ); document.write( "x = 0 \n" ); document.write( "Therefore y = -1/2(0) + 2 \n" ); document.write( " y = 2\r \n" ); document.write( "\n" ); document.write( "So the coordinates (0, 2) is \n" ); document.write( "where it cuts the y axis \n" ); document.write( " |
