Substitute the first coordinate for x in the equation y = 2x - 4 and the second coordinate for y.\r\n" ); document.write( " 8. Simplify the right side of the equation until it is a single number\r\n" ); document.write( " 9. If the number on the right is the same number as the number on the left, then it is a solution to the equation. If not, ignore it.\r\n" ); document.write( "10. write a left parenthesis \"(\" , then\r\n" ); document.write( "11. just to the right of the \"(\", write the first coordinate, then\r\n" ); document.write( "12. just to the right of the first coordinate, write a comma \",\" , then\r\n" ); document.write( "10. just right of the comma, write the second coordinate, then\r\n" ); document.write( "11. finally, just right of the second coordinate, write a right parenthesis, \")\" , then\r\n" ); document.write( "12. That's it! Each ordered pair should look something like this \" {6,7) \", only with different numbers.\r\n" ); document.write( "\r\n" ); document.write( "Edwin\n" ); document.write( " |
