You can put this solution on YOUR website!
The simple way to graph y = x-1 is to generate at least two points, put those on your graph paper and draw a straight line through them.\r
\n" ); document.write( "\n" ); document.write( "Here's how you geneate the required points:\r
\n" ); document.write( "\n" ); document.write( "Use your equation, y = x-1 and choose an integer for x, say x=2, and substitute this into your equation to find the corresponding value of y.\r
\n" ); document.write( "\n" ); document.write( "y = 2 - 1
\n" ); document.write( "y = 1\r
\n" ); document.write( "\n" ); document.write( "So your first point has coordinates of (2, 1) Now repeat this operation with a different value of x, say x = 5.\r
\n" ); document.write( "\n" ); document.write( "y = 5 - 1
\n" ); document.write( "y = 4\r
\n" ); document.write( "\n" ); document.write( "Your second point has coordinates (5, 4)\r
\n" ); document.write( "\n" ); document.write( "Now mark these two locations on your graph paper. Starting at the origin of your graph (where the x-axis crosses the y-axis), go to the right 2 squares (x=2) then up 1 square (y=1) and mark your first point.
\n" ); document.write( "For the second point, again, start at the origin and go right 5 squares (x=5) and then up 4 squares (y=4) and mark your second point.
\n" ); document.write( "Using a straight-edge, draw a line joining these two points.\r
\n" ); document.write( "\n" ); document.write( "You have now graphed the equation: y = x - 1.\r
\n" ); document.write( "\n" ); document.write( "Compare your graph with the graph of y = x - 1 shown below.\r
\n" ); document.write( "\n" ); document.write( "\"graph%28300%2C200%2C-6%2C6%2C-6%2C6%2Cx-1%29\"
