You can put this solution on YOUR website!
Given y = 3x --->(1)
\n" ); document.write( "The point is represented by (x ,y)
\n" ); document.write( "So the point (0 , -------)
\n" ); document.write( "Put x = 0 in the equation(1), we get
\n" ); document.write( "y = 0.
\n" ); document.write( "Therefore the missing values, (0, 0)\r
\n" ); document.write( "\n" ); document.write( "Now again put x = -1, we get
\n" ); document.write( "y = 3(-1) = -3
\n" ); document.write( "Therefore the values are (-1 , -3)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Now again put x = 7 in equation(1), we get
\n" ); document.write( "y =3(7) = 21
\n" ); document.write( "Therfore the value are (7,21)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Hence whenever you are given an equation and the first value \"x\", just substitute to get the missing value.\r
\n" ); document.write( "\n" ); document.write( "(0, 0) (-1, -3) (7, 21)
\n" ); document.write( " \n" ); document.write( "
\n" );
