You can put this solution on YOUR website!
Any line that passes through the origin will pass through the point (0,0). So this means that when x=0, then y=0. Plug these values in to get $\"0=3%280%29%2Bk\"$ . Multiply to get $\"0=0%2Bk\"$ and combine like terms to get $\"0=k\"$ . So the value of k is $\"k=0\"$ meaning that the equation that passes through the origin is $\"y=3x\"$ \n" ); document.write( "
