You can put this solution on YOUR website!
For the coordinate (3, something) the three is the x value. Because in the equation\"4x+%26%238722%3B+3y+=+%26%238722%3B12+\" x is the value of the coordinate, when you substitute in the value for x, when you solve for y, it will give you the y value.
\n" ); document.write( "\"4x-3y=-12\"
\n" ); document.write( "\"4%2A3-3y=-12\"
\n" ); document.write( "\"12-3y=-12\"
\n" ); document.write( "Subtract 12 from both sides
\n" ); document.write( "\"-3y=-24\"
\n" ); document.write( "Divide both sides by -3
\n" ); document.write( "\"y=8\"
\n" ); document.write( "

(3, 8)


\n" ); document.write( "For the next, ( ,-8), -8 is the y value
\n" ); document.write( "\"4x-3y=-12\"
\n" ); document.write( "\"4x-3%28-8%29=-12\"
\n" ); document.write( "\"4x%2B24=-12\"
\n" ); document.write( "Subtract 24 from both sides
\n" ); document.write( "\"4x=-36\"
\n" ); document.write( "Divide both sides by 4
\n" ); document.write( "\"x=-9\"
\n" ); document.write( "

(-9, -8)


\n" ); document.write( "For the next coordinate, ( ,10), 10 is the y value
\n" ); document.write( "\"4x-3y=-12\"
\n" ); document.write( "\"4x-3%2810%29=-12\"
\n" ); document.write( "\"4x-30=-12\"
\n" ); document.write( "Add 30 to both sides
\n" ); document.write( "\"4x=18\"
\n" ); document.write( "Divide both sides by 4
\n" ); document.write( "\"x=9%2F2\"
\n" ); document.write( "

The three coordinates are (3, 8), (-9, -8), and (9/2, 10) \n" ); document.write( "
