You can put this solution on YOUR website!
This is a simple matter of substituting the given values of x or y and solving the equation for the other variable.\r
\n" ); document.write( "\n" ); document.write( "1) y = 2x + 7\r
\n" ); document.write( "\n" ); document.write( "(a)Given (0, ?), substitute x = 0 into the equation and solve for y.\r
\n" ); document.write( "\n" ); document.write( " y = 2(0) + 7
\n" ); document.write( " y = 7\r
\n" ); document.write( "\n" ); document.write( "The ordered pair for (a) is : (0, 7)\r
\n" ); document.write( "\n" ); document.write( "(b) Given (4, ?), substitute x = 4 into the equation and solve for y.\r
\n" ); document.write( "\n" ); document.write( "y = 2(4) + 7
\n" ); document.write( "y = 8 + 7
\n" ); document.write( "y = 15\r
\n" ); document.write( "\n" ); document.write( "The ordered pair for (b) is: (4, 15) Get the idea?\r
\n" ); document.write( "\n" ); document.write( "I'll do (a) of the second problem, then you try (b).\r
\n" ); document.write( "\n" ); document.write( "2) 3x - 7y = 30
\n" ); document.write( "(a) Given (3, ?), substitute x = 3 into the equation and solve for y.\r
\n" ); document.write( "\n" ); document.write( "3(3) - 7y = 30
\n" ); document.write( "9 - 7y = 30 Subtract 9 from both sides.
\n" ); document.write( "-7y = 21 Divide both sides by -7
\n" ); document.write( "y = -3\r
\n" ); document.write( "\n" ); document.write( "The ordered pair for (a) is: (3, -3)\r
\n" ); document.write( "\n" ); document.write( "Try (b), but in this one, you are given the y-coordinate (3) and you are to solve for x. Otherwise, the procedure is the same.
