Any line parallel to the given line 3y-4x=12 i.e., 3y=4x+12 will have the same slope as the given line. In the equation, the slope is given by the ratio of the coefficient of x to coefficient of y. \r \n" ); document.write( "\n" ); document.write( "Naturally, the required line also will have its equation with x and y coefficients same as that of given line. so, let us take the equation as 3y=4x+k. \n" ); document.write( "what needs to be found now is the constant 'k'. Here we go now to find k.\r \n" ); document.write( "\n" ); document.write( "given that the point (1, 4) lies on the line. So, (1, 4) has to satisfy the equation of the line. So, we must choose the constant in such a way that when we plug the values x=1, y=4 in the equation, it should get satisfied. Right?!\r \n" ); document.write( "\n" ); document.write( "clearly, 3(4)=4(1)+k will be satisfied when k=8\r \n" ); document.write( "\n" ); document.write( "so the equation to the required line is 3y=4x+8 \n" ); document.write( " |
