\r
\n" ); document.write( "\n" ); document.write( "Looking at \"y=-2x%2B3\" we can see that the equation is in slope-intercept form \"y=mx%2Bb\" where the slope is \"m=-2\" and the y-intercept is \"b=3\" \r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Since \"b=3\" this tells us that the y-intercept is .Remember the y-intercept is the point where the graph intersects with the y-axis\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So we have one point \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Now since the slope is comprised of the \"rise\" over the \"run\" this means\r
\n" ); document.write( "\n" ); document.write( "\"slope=rise%2Frun\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Also, because the slope is \"-2\", this means:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"rise%2Frun=-2%2F1\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "which shows us that the rise is -2 and the run is 1. This means that to go from point to point, we can go down 2 and over 1\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So starting at , go down 2 units \r
\n" ); document.write( "\n" ); document.write( "\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "and to the right 1 unit to get to the next point \r
\n" ); document.write( "\n" ); document.write( "\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Now draw a line through these points to graph \"y=-2x%2B3\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " So this is the graph of \"y=-2x%2B3\" through the points and \r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Now notice that the graph extends in both directions along the x-axis. So this means that ANY value of \"x\" can be plugged into the function. \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So the domain is all real numbers.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Also, take note that the graph extends in both directions along the y-axis as well. So this tells us that the range is also ANY number.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So the range is all real numbers.
