You can put this solution on YOUR website!
\"3x%2By=5\" Start with the given equation.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"y=5-3x\" Subtract \"3x\" from both sides.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"y=-3x%2B5\" Rearrange the terms.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Looking at \"y=-3x%2B5\" we can see that the equation is in slope-intercept form \"y=mx%2Bb\" where the slope is \"m=-3\" and the y-intercept is \"b=5\" \r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Since \"b=5\" 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 \"-3\", this means:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"rise%2Frun=-3%2F1\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "which shows us that the rise is -3 and the run is 1. This means that to go from point to point, we can go down 3 and over 1\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So starting at , go down 3 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=-3x%2B5\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " So this is the graph of \"y=-3x%2B5\" through the points and \r
