Algebra.Com's Answer #695939 by jim_thompson5910(35256)![]() ![]() ![]() You can put this solution on YOUR website! The graph of the line crosses the x axis when y = 0 \n" ); document.write( "Plug y = 0 into the equation and isolate x\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "4x+5y = 12 \n" ); document.write( "4x+5*0 = 12 \n" ); document.write( "4x+0 = 12 \n" ); document.write( "4x = 12 \n" ); document.write( "4x/4 = 12/4 \n" ); document.write( "x = 3\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "When we plugged in y = 0 and solved for x, we got x = 3. \n" ); document.write( "So those x and y values pair up to get (x,y) = (3,0)\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Therefore, the x intercept is (3,0) meaning that the graph crosses the x axis at 3. \n" ); document.write( " |
