You can put this solution on YOUR website!
1)As a table, make a table with 2 columns and 5 rows. Label the first column \"x\" and the second column \"y\". Then use the coordinates of the given points to fill in the table.
\n" ); document.write( "row 1 has -2 -4
\n" ); document.write( "row 2 has -1 -1
\n" ); document.write( "and so on\r
\n" ); document.write( "\n" ); document.write( "2) As a graph, lay down a standard Cartesian grid (like graph paper). Then plot the 5 given points. If you see a \"curve\" in thyat data, then sketch in the curve\r
\n" ); document.write( "\n" ); document.write( "3) As mapping diagram, draw an ellipse shaped like a \"0\", leave an inch of two of space and then draw a second one to the right of the first (same shape, same size).
\n" ); document.write( "Put all of the x values in the left ellipse (see column one from the table in part 1). Put all the y values in the right ellipse (see column two from the table above).
\n" ); document.write( "Now connect the x values in the left ellipse with the corresponding y values in the roght ellipse. Just draw a line from one to the other. That is the \"map\"
